1. Find a pda that accepts the language L = {a""62n : n >0}. a =

Answers

The PDA accepting the language L = {a^(62n):n>0} has been found.

We have to find a PDA that accepts the language L = {a^(62n):n>0}.

Solution: First of all, let’s discuss the language L = {a^(62n):n>0}.

Here, “a” represents a character and “n” is a natural number greater than 0. Each string of this language has a length equal to 62n, where n is a natural number greater than 0.

If n=1, then the length of string is 62.

If n=2, then the length of string is 124 and so on.

Thus, the length of string is a multiple of 62.

Therefore, we can define a PDA for this language as follows: Consider the transition of a PDA is

Q = {q0,q1}∑

= {a}Γ

= {a, Z0} ∂

δ(q0, a, Z0) = {(q0, aZ0)}

δ(q0, a, a) = {(q0, aa)}

δ(q0, ε, Z0) = {(q1, Z0)}

This PDA accepts the string "a^62n" where n>0. Initially, "Z0" is pushed into the stack. From the start state, the transition is made on every 'a' symbol by pushing it onto the stack. After each of the 62 symbols, we remain in the same state until 62 'a' symbols are pushed onto the stack. We reach the final state after every 62 'a' symbols have been pushed onto the stack. The stack has become empty, and all the 'a' symbols have been consumed.

Thus, this PDA accepts the language L = {a^(62n):n>0}.

Conclusion: Thus, the PDA accepting the language L = {a^(62n):n>0} has been found.

In state q0, q1, and q2, if the PDA encounters any symbol other than 'a' in the input or the stack, it will reject. The PDA accepts if it reaches state q2 with an empty stack.

To construct a Pushdown Automaton (PDA) that accepts the language L = {a^(6n) : n > 0}, where a denotes the symbol 'a', we can use a stack to keep track of the count of 'a's encountered. Here's a description of the PDA:

1. Start in the initial state q0.

2. Read an input symbol. If it is 'a', move to the next step. If it is any other symbol, reject.

3. Push a marker symbol '$' onto the stack to mark the beginning of the input.

4. Read six 'a's from the input. For each 'a', push it onto the stack.

5. After reading six 'a's, while there are more 'a's to read, repeat the following steps:

  a. Read an 'a' from the input and push it onto the stack.

  b. If the top symbol of the stack is 'a', push the new 'a' onto the stack.

  c. If the top symbol of the stack is '$', push the new 'a' onto the stack and transition to state q1.

  d. If the top symbol of the stack is any other symbol, reject.

6. If the input is empty, reject.

7. If the next symbol in the input is not 'a', reject.

8. Pop the top symbol of the stack. If it is 'a', repeat step 8.

9. If the top symbol of the stack is '$' and the input is empty, accept; otherwise, reject.

The PDA transitions are as follows:

q0, a, $ -> q0, a$

q0, a, a -> q0, aa

q0, a, ε -> q1, a

The PDA transitions in state q1 are as follows:

q1, a, a -> q1, ε

q1, ε, $ -> q2, ε

The PDA transitions in state q2 are as follows:

q2, ε, ε -> q2, ε

In state q0, q1, and q2, if the PDA encounters any symbol other than 'a' in the input or the stack, it will reject. The PDA accepts if it reaches state q2 with an empty stack.

Note: The PDA described here assumes that the input consists only of 'a' symbols and ignores any other symbols in the input. If you need to consider other symbols, you can modify the transitions accordingly.

Write a function myfind, that searches a c-string for the first occurrence of the char variable findletter, and returns the position in the c-string where it is found or -1, if findletter is not in the c-string.
You may assume the following variables exist and already have valid information in them:
char cStringtoSearch[81];
char findletter;
int pos;
You may assume that the following code exists in the function main():
pos = myfind(cStringtoSearch,findletter);

cout<<"The first occurrence of" < "is in position "<

Answers

A C-string is a sequence of characters that is terminated by a null character.

A null character is represented as '\0' and is used to denote the end of a string. This string is generally created by using an array of characters in C programming.

A function myfind that searches a C-string for the first occurrence of the char variable findletter can be created using the following steps:

Algorithmic steps:

Step 1: Create a function named "myfind" that takes two arguments, a C-string and a character findletter.

Step 2: Initialize a variable "pos" of type integer to zero.

Step 3: Loop through the C-string using a while loop and keep checking the characters one by one. If the character is equal to the findletter, return the position where the character was found.

Step 4: If the character is not found, return -1 to indicate that the character is not present in the C-string.

Step 5: In the main function, call the function myfind and pass the C-string and the character as arguments. If the return value is -1, print a message indicating that the character was not found in the C-string.

Otherwise, print the position where the character was found in the C-string.

The following code shows an implementation of the myfind function:Code:

int myfind(char cStringtoSearch[], char findletter){    int pos = 0;    while (cStringtoSearch[pos] != '\0') {        if (cStringtoSearch[pos] == findletter) {            return pos;        }        pos++;    }    return -1;}

The code below shows how to call the function and print the result:

Q8) Apply variable length subnet masking to calculate the
addresses of each subnet as well as the host addresses for each
subnet for the following IP address / 16
5 subnets – with 2050

Answers

Applying variable length subnet masking (VLSM) to the given IP address with 165 subnets and 2050 hosts allows for the creation of multiple subnets with varying sizes. This approach enables efficient allocation of IP addresses based on the specific subnet requirements.

To apply variable length subnet masking (VLSM) to the given IP address with 165 subnets and 2050 hosts, we need to allocate subnet addresses and host addresses based on the network requirements. VLSM allows for the creation of subnets with different sizes, optimizing the allocation of IP addresses.

To determine the subnet addresses and host addresses, we start by identifying the number of bits required to accommodate the given number of subnets and hosts. In this case, we need 8 bits to represent 165 subnets (2^8 = 256) and 11 bits to represent 2050 hosts (2^11 = 2048).

Next, we divide the available IP address range into subnets, allocating the required number of bits for the subnet portion and the host portion. Each subnet will have its own subnet address and a range of host addresses. The exact subnet addresses and host addresses can be calculated using the subnetting formula and bitwise operations.

By applying VLSM, we can allocate IP addresses efficiently, using larger subnets for networks with fewer hosts and smaller subnets for networks with more hosts. This allows for optimal utilization of IP address space and efficient routing within the network.

4. What member(s) of the Shape class are not directly accessible to member functions of the Circle
class? Name a way to make them accessible.

Answers

3. Yes, an object of the Circle class can call the setArea() member function of the Shape class because the Circle class is inheriting the public members of the Shape class, including the setArea() function.

4. The private member variable "area" of the Shape class is not directly accessible to member functions of the Circle class.

One way to make it accessible is by declaring a protected setter function for the area variable within the Shape class, such as:

```

class Shape {

private:

double area;

protected:

void setAreaProtected(double a) {

area = a;

}

public:

double getArea() {

return area;

}

};

class Circle : public Shape {

double radius;

public:

void setRadius(double r) {

radius = r;

setAreaProtected(3.14*r*r);

}

double getRadius() {

return radius;

Flowchart required for Rock, Paper, Scissors game.
Rules of the Game:
The objective of Rock, Paper, Scissors is to defeat your opponent by selecting a weapon that defeats their choice under the following rules:
Rock smashes Scissors, so Rock wins
Scissors cut Paper, so Scissors win
Paper covers Rock, so Paper wins
If players choose the same weapon, neither win and the game is played again
Program Specifications
This project requires you to use:
input from the player
print results
at least one branching mechanism (if statement)
at least one loop (while loop)
Boolean logic
Your program will allow a user to play Rock, Paper, Scissors with the computer. Each round of the game will have the following structure:
The program will choose a weapon (Rock, Paper, Scissors), but its choice will not be displayed until later so the user doesn’t see it.
The program will announce the beginning of the round and ask the user for their choice
The two weapons will be compared to determine the winner (or a tie) and the results will be displayed by the program
The next round will begin, and the game will continue until the user chooses to quit
The computer will keep score and print the score when the game ends
The computer should select the weapon most likely to beat the user, based on the user’s previous choice of weapons. For instance, if the user has selected Paper 3 times but Rock and Scissors only 1 time each, the computer should choose Scissors as the weapon most likely to beat Paper, which is the user’s most frequent choice so far. To accomplish this, your program must keep track of how often the user chooses each weapon. Note that you do not need to remember the order in which the weapons were used. Instead, you simply need to keep a count of how many times the user has selected each weapon (Rock, Paper or Scissors). Your program should then use this playing history (the count of how often each weapon has been selected by the user) to determine if the user currently has a preferred weapon; if so, the computer should select the weapon most likely to beat the user’s preferred weapon. During rounds when the user does not have a single preferred weapon, the computer may select any weapon. For instance, if the user has selected Rock and Paper 3 times each and Scissors only 1 time, or if the user has selected each of the weapons an equal number of times, then there is no single weapon that has been used most frequently by the user; in this case the computer may select any of the weapons.
At the beginning of the game, the user should be prompted for input. The valid choices for input are:
R or r (Rock)
P or p (Paper)
S or s (Scissors)
Q or q (Quit)
At the beginning of each round your program should ask the user for an input. If the user inputs something other than r, R, p, P, s, S, q or Q, the program should detect the invalid entry and ask the user to make another choice.
Your program should remember the game history (whether the user wins, the computer wins, or the round is tied).
At the end of the game (when the user chooses ‘q’ or ‘Q’), your program should display the following:
The number of rounds the computer has won
The number of rounds the user has won
The number of rounds that ended in a tie
The number of times the user selected each weapon (Rock, Paper, Scissors)

Answers

To create a flowchart for the Rock, Paper, Scissors game, you will need to incorporate input from the player, print the results, utilize branching mechanisms (if statements), implement a loop (while loop), and apply Boolean logic. The flowchart should allow the user to play against the computer, keeping track of the score and selecting the computer's weapon based on the user's previous choices.

The flowchart for the Rock, Paper, Scissors game will begin by initializing the score counters for the computer and the player. Then, it will enter a loop that continues until the user chooses to quit. Within the loop, the program will prompt the user to enter their choice (Rock, Paper, Scissors, or Quit).

Once the user's choice is obtained, the program will compare it with the computer's randomly selected choice, which remains hidden. Based on the game rules, the winner of the round will be determined, and the corresponding score counter will be incremented. If the round ends in a tie, the tie counter will be increased.

After displaying the results of the round, the program will check if the user has chosen to quit. If not, it will prompt for another round. However, if the user decides to quit, the program will exit the loop and display the final score, including the number of rounds won by the computer, the user, and the ties.

To select the computer's weapon, the program will keep track of the user's previous choices. It will count how many times each weapon has been selected and determine the user's most frequent choice. Based on this information, the computer will choose the weapon most likely to beat the user's preferred weapon. In rounds where there is no clear preference, the computer can select any weapon.

By following this flowchart, you can create a Rock, Paper, Scissors game that incorporates the specified rules and gameplay mechanics.

It first creates a copy of the array using the clone method of the array class, and then sorts the copied array using the sort method of the Arrays class. After sorting the copied array, the method checks if the length of the array is even or odd using the modulus operator.

If the length is even, it returns the average of the middle two elements. If the length is odd, it returns the middle element.  To call this method from main, you would need to create an array of integers and pass it as a parameter to the getMedian method.

As we know that a is the power of 2, it can be represented as follows:a=2^kWe can write the given equation as follows:1-1 n 1 h=[(2^(-kc)) + (2^(-2kc)) +...+(2^(-nc)) +cm] mod size= [(Σ 2^(-kc))] mod size i=1Now, we can write the above equation as:1-1 n 1 h= [(1-2^(-kc+n+1)) /(1-2^(-kc))] mod size i=1Now we will find the value of 2^(-kc+n+1): 2^(-kc+n+1)=2^n * 2^(1-kc)=2^n / a

Now we will substitute this value in the above equation:1-1 n 1 h= [(1-2^n/a) /(1-2^(-kc))] mod size i=1We will further simplify the equation by writing 2^(-kc) as (2^k)^-c, and a=2^k:1-1 n 1 h= [(1-2^n/2^k) /(1-2^(-k*c))] mod size i=1= [(1-2^(n-k)) /(1-2^(-k*c))] mod size i=1This is the final equation. The given equation can be rewritten as [(1-2^(n-k)) /(1-2^(-k*c))] mod size.

[8 Marks] Imagine you are an attacker who wishes to launch an Amplification attack on a target host, but you do not want to utilise DNS servers. List and explain four criteria to select an alternative set of servers to utilise in your attack?

Answers

When selecting an alternative set of servers to launch an Amplification attack without utilizing DNS servers, four criteria to consider are network bandwidth, server response time, amplification factor, and accessibility.

1. Network Bandwidth: Choose servers with high network bandwidth to maximize the potential impact of the attack. Servers with larger bandwidth will allow for greater amplification of the attack traffic, potentially overwhelming the target host.

2. Server Response Time: Opt for servers with fast response times to ensure rapid and efficient amplification. Servers that respond quickly will allow for a higher rate of attack traffic generation, increasing the overall effectiveness of the attack.

3. Amplification Factor: Look for servers that have a high amplification factor, which refers to the ratio of the response data size to the size of the attack request. Servers with a larger amplification factor will generate more traffic towards the target host, maximizing the impact of the attack.

4. Accessibility: Ensure that the selected alternative servers are accessible and reachable. Servers that are easily accessible will enable the attacker to establish a connection and launch the attack effectively. Additionally, consider the geographical distribution of the servers to ensure widespread coverage and potential diversification of attack sources.

By carefully considering these criteria, an attacker can select an alternative set of servers that possess the desired characteristics to launch an Amplification attack without relying on DNS servers, increasing the effectiveness and impact of the attack.

Write a C program that works as described below and prints the desired messages as desired:
Note: to start with 4 and 5. You can base the example shown in the lessons.
After the program starts , it should only show >> (do not print other messages.):
>>
Then start the user's command with a new processi fork to run it with the exec family system call and have the parent process wait until this process is finished.
If the command that the user entered was not found when running the command, that is, if the exec function fails:
Because this error may be caused by path, use the exec family function to find the path of this command with one of the following commands. For example, if you want to be found 'ls'
$ which ls
$ whereis ls
$ command -v ls (not: alias oldugunda pathi vermiyor)
If the given program name is in the current path, then run the program again using the current path.
$ pwd ile current pathi bulabilirsiniz
$ locate -w path/name yada
You can still make different combinations: $ locate -b basename | fgrep -w path
If it is not a current path and is not defined in the system path, that is, both a.i and a. Ii, if it has given an error, then print an error message as follows. For example, if the text the user enters is a name, the screenshot should be as follows (pay attention to the number of lines and so on):
>> name
name: command not found

In the above 2.a and 2.b, after running the desired commands with the exec, it is requested that the outputs be read by the parent process from a file named file:
Before running Exec in child process , create a file named file and redirect the stdoutu to that file. You are asked to do so as follows.
/*In CHILD PROCESS*/
int new_out = open("file", O_WRONLY | O_CREAT | O_TRUNC, 0666);

/*check for errors*/
/*exec... */
/*restoring stdoutu*/
dup2(saved_out, 1); /*duplicate saved_out to 1*/
close(saved_out);
close(new_out);
Open this file in parent process to read it and create a path name.

The paragraph describes a C program that executes user commands, handles errors, redirects output to a file, reads the output from the file, and displays it on the screen.

What does the provided paragraph describe?

The provided paragraph describes a C program that executes user commands using the `exec` family of system calls, handles errors when the command is not found, redirects the command's output to a file, and reads the output from the file to display it in the parent process. The program follows the following steps:

1. Displays `>>` prompt.

2. Reads the user's command.

3. Forks a new process to run the command using `exec`.

4. If the command is not found, uses the `exec` function to find the command's path.

5. If the command is in the current path, reruns the program using the current path.

6. If the command is not in the current path and not defined in the system path, prints an error message.

7. In the child process, creates a file named "file" and redirects the stdout to that file using file descriptors.

8. Executes the desired command using `exec`.

9. In the parent process, opens the file "file" to read the command's output.

10. Redirects the output back to stdout and prints it in the parent process.

11. Uses system calls for file read and write operations instead of standard library functions like `fopen`.

Overall, the program executes user commands, handles errors, redirects output to a file, reads the output from the file, and displays it on the screen.

Add Setter mutator for Java code below and

public class Admin {
private String employeeId, employeeDepartment, adminDate;
private int rateEmployee;
private float to

Answers

The Java code provided defines a class named Admin without a setter mutator. We can add the setter mutator methods and create a testAdmin class to run it.

To add setter mutator methods to the Admin class in Java, we can define public methods that allow us to modify the private fields of the class. Here's an example of adding setter mutator methods for the fields:

```java

public class Admin {

   private String employeeId, employeeDepartment, adminDate;

   private int rateEmployee;

   private float totalSalary;

   // Getter methods here...

   // Setter methods

   public void setEmployeeId(String employeeId) {

       this.employeeId = employeeId;

   }

   public void setEmployeeDepartment(String employeeDepartment) {

       this.employeeDepartment = employeeDepartment;

   }

   public void setAdminDate(String adminDate) {

       this.adminDate = adminDate;

   }

   public void setRateEmployee(int rateEmployee) {

       this.rateEmployee = rateEmployee;

   }

   public void setTotalSalary(float totalSalary) {

       this.totalSalary = totalSalary;

   }

}

```

To create a testAdmin class to run the code, you can define a separate class that includes a main method where you can instantiate an object of the Admin class and use the setter methods to set the values. Here's an example:

```java

public class TestAdmin {

   public static void main(String[] args) {

       Admin admin = new Admin();

       admin.setEmployeeId("123");

       admin.setEmployeeDepartment("IT");

       admin.setAdminDate("2023-06-13");

       admin.setRateEmployee(10);

       admin.setTotalSalary(1000.0f);

       // You can access the values using getter methods here...

   }

}

```

In the testAdmin class, we create an instance of the Admin class and use the setter methods to set the values of the fields. Then, you can access the values using the getter methods.

In Python, the `break` statement is used to exit from the innermost loop and stop iterating through items.

It can be used with `while` and `for` loops.

The break statement is used to immediately terminate a loop in Python.

When the `break` statement is executed, the current loop ends and the flow of control goes to the next statement after the loop.

If the `break` statement is used in a loop, the loop’s `else` clause is not executed.

The following is an example of the `break` statement in a `for` loop:```
for x in range(6):
 if x == 3:

Answers

The five addressing modes, Immediate addressing, Register addressing, Base addressing, PC-relative addressing, and Pseudodirect addressing, represent the architecture of the MIPS processor because each of these addressing modes has a specific advantage.

Here is a brief explanation of the reason for each addressing mode:Immediate addressing:It is a type of addressing mode in which the operand is in the instruction. Immediate addressing mode allows operands to be encoded in the instruction itself, which makes it simple and easy to use, and eliminates the need to reference memory.Register addressing:This type of addressing mode makes use of a register to store data instead of main memory. Register addressing mode can increase the speed of operation because it reduces the time required to access memory.

This is because it is faster and more efficient than using absolute addressing mode. Pseudodirect addressing : This type of addressing mode is a variant of PC-relative addressing. The difference is that instead of using an offset, it uses the full address of the target. This is useful in the MIPS architecture because it simplifies the hardware needed to implement jumps and branches.

Answers

The component stimulated represents the part of the system impacted by a stimulus in a quality attribute scenario, recoverability evaluates the system's recovery speed in case of failures, and a conceptual view offers a high-level understanding of design elements in software architecture.

In a quality attribute scenario, the component stimulated refers to the specific software or hardware component that is being acted upon or triggered by a stimulus. The stimulus represents an event or action that impacts the system, and the component stimulated is the part of the system that responds to that stimulus.

In the AIB case study, recoverability is a quality factor that evaluates how fast the system can be restored or recovered in the event of a software or hardware failure. It focuses on the system's ability to recover from failures and resume normal operation in a timely manner, minimizing downtime and ensuring continuity of service.

A conceptual view in software architecture provides a high-level view of important design elements and concepts. It focuses on capturing the essential aspects of the system's structure, functionality, and relationships between major components. It helps stakeholders understand the overall architecture and provides a foundation for further detailed design and implementation.

The code view, on the other hand, focuses on the low-level details of the implementation, such as specific lines of code or algorithms. The module view emphasizes the organization and composition of software modules or components. The execution view captures the dynamic behavior of the system, including how different components interact and collaborate during runtime.

In summary, the component stimulated in a quality attribute scenario represents the part of the system affected by a stimulus, recoverability evaluates the system's ability to recover from failures, and a conceptual view provides a high-level understanding of important design elements in software architecture.

Answers

The question appears to be incomplete and unclear, and some terms and phrases make no sense. However, I will attempt to answer the parts that are clear and make sense. MIPS is a Reduced Instruction Set Computer (RISC) instruction set architecture. The ADDU instruction adds two 32-bit unsigned integers, whereas ADD adds two 32-bit signed integers.

An overflow occurs when the result of an arithmetic operation is too large or too small to be represented in the allocated space in memory. An overflow occurs when the result of an operation requires more bits than the available memory space. MIPS processors handle overflow conditions by setting the overflow flag when an overflow occurs.

MIPS assembly code to detect overflow after an ADDU instruction ADDU $t1, $t2, $t3  

# add the numbers SLTU $t4, $t1, $t2  

# set $t4 to 1 if $t1 < $t2, 0 otherwise SLTU $t5, $t1, $t3  

# set $t5 to 1 if $t1 < $t3, 0 otherwise XOR $t6, $t4, $t5  

# XOR $t4 and $t5, put the result in $t6 BEQ $t6, $zero, L2

# jump to L2 if the result of the XOR is 0  

# (i.e., if the two SLTU are equal)

The code uses the SET LESS THAN UNSIGNED (SLTU) instruction to compare $t1 to $t2 and $t1 to $t3. If either comparison is true (i.e., the condition is met), the corresponding $t4 or $t5 is set to 1.

The code then uses the eXclusive OR (XOR) instruction to compare $t4 and $t5. If they are equal, the result is zero and the code jumps to L2. Otherwise, the code continues execution.

You are required to store a lot of data in its raw unstructured form. Can you use a typical data warehouse to do this? If not, what should be used?

Answers

Data warehouses are an excellent tool for storing, processing and extracting business intelligence from structured data. These databases are well-structured and allow organizations to make data-driven decisions based on their existing data.

However, when it comes to storing unstructured data, such as text, images, videos, and audio, data warehouses are not an ideal choice. Unstructured data is not a good fit for traditional database systems. Because of the size, format, and variability of unstructured data, storing it in a standard database would result in massive file sizes, poor performance, and limited searchability, making it nearly impossible to extract useful information. As a result, organizations must use different technologies to store, process, and access unstructured data. Unstructured data should be stored in a data lake rather than a data warehouse. Data lakes are similar to data warehouses in that they store large amounts of data, but they are designed to store raw, unstructured data instead of structured data. As a result, data lakes are ideal for storing unstructured data, such as images, videos, and audio, which cannot be accommodated by traditional database systems. Data lakes also enable enterprises to aggregate and process data from various sources in real time.

Assume a home is connected to an Internet Service Provider's (ISP) access point with a 105-meter optical fiber at 150 Mbps. The speed of signal in an optical fiber is approximately 70% of the speed of light, the latter itself being 300,000 m/s. The ISP uses a sliding-window protocol (see Lecture 1.) Calculate the BDP over this optical fiber. (1 mark) b) What should be the minimum window size in order to get 100% efficiency; i.e., no sender idle time? (3 marks) c) How does this minimum window size compare to BDP? Based on this, what is the physical meaning of BDP? (2 marks) d) Assume the ISP moves the access point for this home further away. As a result, the optical fiber length becomes 210 meters. What will be the efficiency if we still use the same window size as before? To reach 100% efficiency again, what should be the new window size? (2 marks) e) In all of the above, does the size of the packet have any impact on efficiency? Explain. (2 marks)

Answers

The bandwidth-delay product (BDP) is obtained by multiplying the bandwidth of the link by the round-trip time (RTT). Assume that a home is connected to an Internet Service Provider's (ISP) access point using a 105-meter optical fiber at a speed of 150 Mbps.

The speed of light in an optical fiber is roughly 70% of the speed of light, which is 300,000 m/s. The ISP uses a sliding-window protocol (see Lecture 1.)

The packet transmission time should be equal to the round-trip time (RTT), so the window size should be equal to the bandwidth-delay product divided by the packet size. Therefore, the minimum window size to achieve 100% efficiency is given by: Window size = BDP / packet size = 150,000,000 * 0.001 / 1460 = 102740 b) Physical meaning of BDP and its comparison with the minimum window size: The bandwidth-delay product (BDP) indicates the maximum number of bits that can be transmitted on a network link, taking into account the propagation delay. The physical meaning of the BDP is that it is the amount of data that is "in transit" on the network.

Assume a priority queue implementation using a max-heap. Consider the following elements: I - W - T-S-K-G-Z-P-M-Q-U-C-D a) Construct/draw a heap that contains these elements. b) Draw the array-representation of the priority queue constructed in part a. c) enqueue() the following elements in that order (show your workout on the heap drawing): A-F-L-X d) dequeue() three times. Show your workout. e) Draw the array-representation of the priority queue after applying the steps in parts c and d.

Answers

a) The max-heap for the given elements is shown below. It is constructed using the following steps:Arrange the elements in an array, where the first element is the root node and the last element is the rightmost node in the last level.

Build a complete binary tree by placing the elements level-by-level from left to right so that the tree is as full as possible from left to right, with the last level filled in from left to right.Place the largest element (W) at the root node and let its left and right children be T and S, respectively. Repeat the process recursively for the remaining elements in the tree, such that each element is greater than or equal to its children.

The resulting max-heap for the given elements is shown below:b) The array representation of the priority queue constructed in part a is as follows:I W T S K G Z P M Q U C DThe array representation is obtained by traversing the elements in the heap level-by-level from left to right and writing them out as a linear array. The root node (W) is at the beginning of the array, followed by its left and right children (T and S), and so on.c) The elements A, F, L, and X are enqueued in that order by adding them as leaf nodes to the bottom level of the heap and then swapping them with their parents until the heap property is restored.

The workout for the first dequeue operation is shown below:e) The array representation of the priority queue after applying the steps in parts c and d is as follows:F L T S K G Z P M Q U C D X IThe array representation is obtained by traversing the elements in the heap level-by-level from left to right and writing them out as a linear array. The new root node (F) is at the beginning of the array, followed by its left and right children (L and T), and so on.
