1. The correct statement regarding the command `y = list(set(x))` is: The list `x` must have a length that is smaller than or equal to the length of `y`.
When `y = list(set(x))` is executed, it creates a new list `y` by applying the `set()` function to the list `x` and then converting it back to a list using the `list()` function. The `set()` function removes any duplicate elements from `x` since sets cannot contain duplicate values. Therefore, `y` will have the same elements as `x`, but any duplicates will be removed. As a result, `y` may have a length that is smaller or equal to the length of `x`, but it will not be longer.
2. The features that are not part of an abstract data type (ADT) are: the programming language being used and how to implement the retrieval of data.
An abstract data type (ADT) is a high-level description of a data structure along with the operations that can be performed on it, without specifying the implementation details. It defines the behavior and properties of the data structure, but it does not depend on the programming language or the specific implementation techniques. The programming language being used is a separate concern and can vary depending on the application and the choice of implementation. Similarly, how to implement the retrieval of data is an implementation detail that is specific to the chosen programming language and the design decisions made during the implementation process. The other features mentioned, such as the types of attributes being used, how much memory the data takes up, and how much time it takes to retrieve or store the data, are all relevant aspects of an ADT as they define the characteristics and behavior of the data structure.

Use the given class Queue. java (in the submission folder on D2L. Please do not change any content of Queue.java) to implement the Radix Sort algorithm using queues (each bucket is a queue) we discussed in class. Call the program RadixSortYourName.java. The program prompts the user to enter the number of input values, then reads that many positive integer values and store them in an array of type integer (call it inputs). Next, the program applies radix sort algorithm we discussed to the values stored in array inputs, and then prints out the content of the array before and after being sorted. (There is no limitation of the number of digits of each integer. For example, your program must be available on any integer possible number such as 492195 or 9817352). Notes: 1. DO NOT CONVERT INTEGERS TO STRINGS to count or extract digits. They should be manipulated as numeric integer values. 2. Radix sort requires digit extraction. For example, given a value 149 , you need to extract 1,4 , 9 separately from the value. To do so, implement a separate method in class RadixSortYourName (call it ExtractDigit) to do this job. Tips: you can use the division (/) and mod (\%) in your method to get a digit at a given position of a value. 3. Radix sort also needs to have another method (call it DigitCount) to count how many digits are in a value. For example, given a value 149, you need to count how many digits in this value which is 3. Tips: you can use the Math.log 10 method, but you need to modify the result once you call the Math.log 10 method to get the correct result. Make sure to allow re-run: How many integer numbers do you have?: 6//<− user input Enter 6 integer numbers: 213346572954145//<− user input Inputs array before sorting (radix): 213,3465,7,29,541,45 Inputs array after sorting (radix): 7,29,45,213,541,3465 Do you want to continue?

GOTO INNER_LOOP ; If the delay register is not zero, repeat the inner loop
GOTO DELAY_LOOP ; Repeat the delay loop
; Data memory allocation
DELAY_REG EQU 0x20 ; Delay register
END
To calculate the size of the delay, we need to determine the number of instructions executed in the loop and multiply it by the instruction cycle time.
The code snippet has two nested loops. Let's analyze it step by step:
a. First loop:
MOVLW 200
MOVWF R2
This instruction loads the value 200 into register R2.
b. Second loop:
AGAIN
MOVLW 250
MOVWF R3
HERE
NOP
NOP DECF R3, F
BNZ HERE
DECF R2, F
BNZ AGAIN
RETURN
To calculate the delay, we need to determine how many times the second loop will be executed. In this case, the value of R2 is initialized to 200, and it will be decremented by 1 in each iteration of the second loop. Therefore, the second loop will execute 200 times.
Assuming the crystal frequency is 4MHz and the instruction cycle time is calculated as follows:
Instruction cycle time = 1 / Crystal frequency= 1 / 4MHz= 0.25usTo find the size of the delay, we multiply the number of instructions (200) by the instruction cycle time:
Delay size = Number of instructions * Instruction cycle time= 200 * 0.25us= 50usSo, the size of the delay in this code snippet is 50 microseconds.
The oscillator frequency is equal to the reciprocal of the instruction cycle time. Given that the instruction cycle time is 1.25 microseconds, we can calculate the oscillator frequency as follows:
Oscillator frequency = 1 / Instruction cycle time= 1 / 1.25us= 0.8MHzTo find the instruction cycle, we can use the reciprocal of the crystal frequency. Given that the crystal frequency is 20MHz, the instruction cycle can be calculated as follows:

Enrollment
The SQL code you've provided joins the Student and Person tables based on their common attributes, Std SSN and SSN. In the joined table, it retrieves and outputs the Std SSN, FirstName, Last Name, and Major columns. The WHERE clause selects the Student.
Std SSN column is IN (included in) the subquery, which selects the Std SSN column from the Enrollment table. As a result, the SQL query will output the Std SSN, FirstName, Last Name, and Major columns for all students whose StdSSN appears in the Enrollment table. It's worth noting that the subquery and the IN operator are used to link the Student and Enrollment tables indirectly through the common attribute, Std SSN. The JOIN clause is used to combine columns from one or more tables into a single table. It is used to join columns from one table to another table. In this case, it joins the Student and Person tables based on their shared attribute, SSN, using the INNER JOIN syntax. The SELECT statement is used to retrieve data from one or more tables.

Point:2 4.Assumed: char *str="hello,CQUPT.", How to output "CQUPT"? A puts(str[6]); B puts(str+6); C puts(*(str+6));
In order to output "CQUPT" from the given string "hello,CQUPT.", we need to use the concept of pointers and arrays. Given that we have a character pointer variable `char *str` which points to the given string "hello,CQUPT.", we can use the following methods to output "CQUPT":A) puts(str[6]);
The `puts()` function is used to output a string to the standard output stream (stdout). Here, `str[6]` refers to the character at the 6th index of the string "hello,CQUPT.", which is 'C'. But since `puts()` expects a string as an argument, the output of this statement would be incorrect. It would output only the character 'C', and not the whole string "CQUPT".
So, option A is incorrect.B) puts(str+6); The correct method to output "CQUPT" is to use the pointer arithmetic to point to the memory location of the 'C' character, which is the 6th character in the string. The `puts()` function can then be used to output the string starting from this location until it encounters a null character.
The expression `str+6` means that we are adding an offset of 6 bytes to the base address of the string, which will point to the memory location of the 'C' character. This method is correct, and hence option B is the correct answer.C) puts(*(str+6)); The expression `*(str+6)` is equivalent to `str[6]`, and both of these expressions point to the character 'C'.
But since `puts()` expects a string as an argument, the output of this statement would be incorrect. It would output only the character 'C', and not the whole string "CQUPT". So, option C is incorrect.Therefore, the correct answer is option B) puts(str+6).

With examples, indicate how functions, objects, and classes are used in object- oriented programming. Explain the concept of arrays and the index of an array. The While Loop is a repetition statement and the if statement is a condition statement. How different is repetition statement from a conditional statement? The program below has syntax mistakes. Identify the mistakes Explain why the mistake Correct the mistakes The program #include const int x = 11.213 const y = 15.6 int main() { This section is worth (2) int k, L; int m, n; L = 7; m = 3.00; L = L +n; a = L +x; cout << a << endl; z = y* 36.75; cout << "Wages = " << z << endl; return 0; }
The variable 'n' should be of data type float and not int.The statement 'k' is declared, but it is not used anywhere in the program.The statement 'z' is not declared.Explanation: The program has syntax errors that would not allow it to compile. The errors identified in the program are fixed as explained above.
Roles of compilers in C++ programming:A compiler is a program that compiles source code and generates a machine-readable object code. The roles of compilers in C++ programming are as follows:It detects syntax and type errorsChecks code quality for efficiencySaves the output to an executable fileFunctions, objects, and classes used in object-oriented programming:Object-oriented programming (OOP) is a programming style that emphasizes objects. An object is an instance of a class in OOP, and it has its properties and methods. Functions, objects, and classes are the main components of object-oriented programming.Functions: A function is a block of code that performs a specific task. It is a self-contained unit of code that returns a value.Objects: In OOP, an object is an instance of a class. Objects contain data and methods, which allow them to interact with each other and with the program as a whole.Classes: A class is a blueprint for creating objects. It is a user-defined data type that contains data members and member functions.Arrays and the index of an array:In C++, an array is a collection of elements that are of the same data type. It is used to store a list of items. The index of an array is the position of an element in the array. It starts from 0 and goes up to n-1, where n is the number of elements in the array.Repetition statement vs. conditional statement:A conditional statement is an “if-then” statement that tests a condition. It is used to perform an action based on the result of the condition. A repetition statement is used to repeat a block of code until a certain condition is met. While loop is an example of a repetition statement.Syntax mistakes in the program:#include using namespace std;const int x = 11;const float y

(10 marks) The Model View Controller (MVC) pattern is used in web development to structure an application. (a) (4 marks) Describe the job of the Controller in this pattern and how it interacts with the Model and the View to make the application work. (b) (6 marks) In a real-estate web application structured using the MVC model, describe how a GET request containing a form submission to search for a house might be processed. Eg. "First the (Model or View or Controller) accepts the HTTP request; then..."
(a) HTTP Methods:
1. Submitting a login form: POST method should be used. When submitting a login form, sensitive information such as the username and password is being sent. Using the POST method ensures that this data is sent in the body of the request, which is more secure compared to sending it in the URL as with a GET request.
2. Submitting a search form to a search engine: GET method should be used. When submitting a search form, the request is intended to retrieve information from the server. The parameters of the search, such as keywords, can be included in the URL as query parameters. Using the GET method allows for bookmarking and sharing the search results.
3. Requesting a page containing your current bank balance: GET method should be used. Requesting a page that contains sensitive information, such as a bank balance, doesn't involve submitting any data. The GET method is suitable for retrieving data from the server without modifying it.
4. Submitting a form to pay a bill from your bank account: POST method should be used. Paying a bill involves modifying data on the server (deducting the bill amount from the bank account). Using the POST method ensures that the sensitive information, such as the payment amount and recipient, is sent securely in the request body.
(b) Differences in form data submission:
With a GET request, the form data is appended to the URL as query parameters. For example, if submitting a search form with the keyword "house" and the location "New York," the URL might look like: `https://example.com/search?keyword=house&location=New+York`.
(c) Redirect response:
A redirect response is an HTTP response (status code 302 Found or 303 See Other) that instructs the browser to make a new request to a different URL. It is commonly used for URL redirection or to redirect users after certain actions.
A typical redirect response includes the following main parts:
Status line: Contains the HTTP version and the status code (e.g., HTTP/1.1 302 Found).Location header: Specifies the new URL that the browser should request.Other response headers (optional): Additional headers may be included depending on the specific use case.When the browser receives a redirect response, it automatically follows the instructions and sends a new request to the URL specified in the Location header. This allows the server to redirect the user to a different page or resource.
4. MVC pattern in web development:
(a) Controller's job and interaction with Model and View:
The Controller in the MVC pattern acts as an intermediary between the Model and the View. Its main job is to handle user input, process it, and update the Model accordingly. The Controller also communicates with the View to update the user interface based on the changes in the Model.
The Controller performs the following tasks:
1. Receives user input from the View.
2. Validates and processes the input.
3. Updates the Model based on the input and business logic.
4. Notifies the View about changes in the Model.
5. May retrieve data from the Model and provide it to the View for display.
The interaction between the components can be summarized as follows:
The View sends user input to the Controller.The Controller updates the Model basedon the input.The Model notifies the Controller of any changes.The Controller updates the View with the updated data.The View renders the updated data to the user.(b) Processing a GET request with a form submission in a real-estate web application:
First, the Controller accepts the HTTP request.The Controller extracts the form data from the request.The Controller validates the form data, ensuring that all necessary fields are provided and correctly formatted.The Controller interacts with the Model to perform the search based on the form data.The Model retrieves relevant data from the database or other data sources.The Controller receives the search results from the Model.The Controller passes the search results to the View.The View renders the search results, displaying them to the user.About Model-View-Controller (MVC)Model-View-Controller or MVC is a method for creating an application by separating the data from the view and how to process it. In its implementation, most frameworks in web applications are based on the MVC architecture.

Let the time taken to switch between user and kernel
modes of execution be t1 while the time taken to switch between two
processes be t2. Which of the following is TRUE?
1) t1 <
The time taken to process switch is more than that of switch between user and kernel, because for process switch it is need to move from user to kernel mode. So, option A: t₁<t₂ is the correct answer.
The statement t1 < t2 indicates that the time required for a context switch between user and kernel modes of execution is shorter than the time needed for a context switch between two processes.
This implies that transitioning from user mode to kernel mode or vice versa is a faster operation compared to switching between different processes. The exact values of t1 and t2 are not provided, so we cannot determine the specific duration of each context switch.
However, based on the given statement, we can conclude that the context switch between modes of execution is generally more efficient and quicker than the context switch between processes. Therefore, the correct answer is option A.

The Python program that implements the described functionality using a binary search tree is given in the code attached.
To be able to use this program, one need a file called "records. csv" in the same folder as the Python program. This file should have names and dates in the format "name,date".
The software takes information from a CSV file and puts it into a special kind of list called a binary search tree. First, it asks the person to type in a name they want to find. If the name is there, it shows the connected information. If the name is not there, it shows " not found.

1. Your program should be named as: Merge.java
The merging process described in this assignment is trivial and slow. There exists an order of magnitudes faster method for
this merge process by using the priority queue data structure.
The Merge.java program involves merging two sorted integer arrays. The program should use the priority queue data structure, which is faster than the trivial method described in the assignment. The priority queue data structure is implemented using the Priority Queue class in Java.
The program should prompt the user to input the sizes of the two arrays. It should then create two arrays of the specified sizes and populate them with random integers between 1 and 1000. The program should print the two arrays before merging them.
The merging process involves creating a priority queue and adding the first elements of the two arrays to it. The smallest element is then removed from the priority queue and added to the merged array. The next element from the array that contained the removed element is added to the priority queue. This process is repeated until all elements have been merged.
The program should print the merged array after the merging process is complete. It should also print the time taken to merge the arrays using the priority queue data structure. This can be done by measuring the system time before and after the merging process using the System.currentTimeMillis() method.

The following for loop is an infinite loop: for(int j = 0; j < 1000;) i++; 12. Assume that the class Bird has a static method fly(). Ifb is a Bird, then to invoke fly, you could do Bird.fly(); 13. The versions of an overloaded method are distinguished by the number, type, and order of 14. A command-line argument is data that is included on the command line when the interpreter -5. Java arrays can store primitive types and Strings but cannot store any type of Object other 16. A Java main method uses the parameter (String() variable) so that a user can run the program and supply command-line parameters. Since the parameter is a String array, however , the user does not have to supply any parameters. 17. An array index cannot be a float, double, boolean, or String. 18. Given the following statement, where CD is a previously defined class, then mycollection[3] is a CD object. CD[] mycollection = new CD [200]; 19. In a two-dimensional array, both dimensions must have the same number of elements, as in my_array[10][10]. 20. One of the advantages of linear search is that it does not require its data to be sorted.
The given for loop is an infinite loop as the increment statement is missing within the loop body. To invoke the static method `fly()` of the `Bird` class, you can use `Bird.fly()`. Overloaded methods are distinguished by the number, type, and order of their parameters.
1. The given for loop `for(int j = 0; j < 1000;) i++;` is an infinite loop because the increment statement for `j` is missing. Without the increment, the loop condition `j < 1000` will always remain true, causing an infinite loop.
2. To invoke the static method `fly()` of the `Bird` class, you can use the class name followed by the method name and parentheses: `Bird.fly();`. This syntax is used to call static methods that belong to a class rather than an instance of the class.
3. Overloaded methods in Java have the same name but different parameter lists. The versions of an overloaded method are distinguished by the number, type, and order of their parameters. This allows multiple methods with the same name to perform different actions based on the arguments passed to them.
4. Java arrays can store primitive types (such as int, float, boolean) and reference types (such as String), but they cannot directly store objects of other classes. However, you can create an array of object references and assign objects of different classes to those references.
5. The main method in Java is the entry point of a program and can accept command-line parameters. The parameter `(String[] variable)` allows the program to receive arguments from the command line. However, it is not mandatory to supply command-line parameters, and the program can run without any arguments.
6. Array indices in Java must be of integer type. They cannot be float, double, boolean, or String values. Only integer values can be used to access elements in an array.
7. The statement `CD[] mycollection = new CD[200];` creates an array named `mycollection` that can store objects of the `CD` class. The array has a length of 200, meaning it can hold 200 `CD` objects. The expression `mycollection[3]` refers to the fourth element in the array, which is a `CD` object.
8. In a two-dimensional array in Java, both dimensions must have the same number of elements. For example, `my_array[10][10]` creates a two-dimensional array with 11 rows and 11 columns, totaling 121 elements.
9. One of the advantages of linear search is that it does not require the data to be sorted. Linear search is a simple search algorithm that sequentially checks each element in a list or array until a match is found. It is efficient for small data sets or unsorted data, but its performance degrades for larger data sets.

What's the difference between a hardlink and a symlink (symbolic link)?
A symlink (symbolic link) and hardlink are the two types of links used in Linux and Unix to create a link between a file and another file in the system.
In this regard, this article will explain the difference between these two types of links in Linux. Read on!Difference between a hardlink and a symlinkA hardlink is simply a reference to the original file's inode number, while a symlink (symbolic link) is a file that points to another file's path rather than its inode number. Therefore, if you create a hardlink, the link points directly to the data on the disk, while with a symbolic link, the link points to another path in the file system.
A symbolic link is a file that contains a reference to another file, while a hard link is a reference to an inode number. Therefore, if you delete the file pointed to by a hardlink, the link will still exist, pointing to nothing. However, if you delete the file pointed to by a symbolic link, the link will be invalid. In summary, a hardlink is simply a pointer to the original file, while a symbolic link is a file that points to another file's path rather than its inode number.

Then • Normalization by decimal scaling 73,600 - 54,000 = 1.225 16,000 v= 10 Where j is the smallest integer such that Max(v'D < 1 52
Normalization is a technique used to standardize the data of a given dataset in order to make it more useful and efficient for analysis. This process involves converting all the data in the dataset to a standardized format, which can be achieved through various methods like min-max normalization, z-score normalization, and decimal scaling.
The following are the different types of normalization techniques:
Min-Max Normalization:
This is the process of scaling and shifting values in the data so that they fall within a range of 0 and 1. It is represented by the formula V= v-min (new_maxı-new_min.) + new_min. This formula is used to normalize the income range between $12,000 and $98,000 to [0.0, 1.0). Here, $73,000 is mapped to 73,600 -12,000 (1.0-0)+0=0.716.
Z-Score Normalization:
The z-score normalization is used to transform data into a standard normal distribution with a mean of zero and a standard deviation of one. This technique is represented by the formula v= - Mi / o. This formula is used to normalize y = 54,000, o = 16,000, where v= (54,000 - 0) / 16,000 = 3.375.Normalization by Decimal Scaling:The normalization by decimal scaling is used to shift decimal places of numbers in the data to achieve a normalized form. This is done by dividing all the numbers by a power of 10 that shifts the decimal point to the left of the number.
The formula used in this technique is v = x / 10^j. Here, j is the smallest integer such that Max(v'D < 1. The normalization is done by calculating v = (73,600 - 54,000) / 10^4, where v = 1.26.

Eliminate derivation from next round only if prefix of w doesn't match sentential form or if sentential form| > w4 or if sentential form is all terminals and does not match w
To find the left-most derivation for the given grammar and input string, "w = abab," using the brute force parsing algorithm, we follow the steps outlined in Chapter 5.2 Power Point slides:
1. Start with the start symbol S and the input string "w = abab."
2. Apply the production rules of the grammar, one by one, to expand non-terminals until the input string is derived.
The given grammar G3 is:
S -> SA
S -> be
A -> babe
A -> aS
Let's proceed with the derivation:
Round 1:
S -> SA (using S -> SA production rule)
-> beA (using A -> be production rule)
-> bebabe (using A -> babe production rule)
Round 2:
S -> SA (using S -> SA production rule)
-> beA (using A -> be production rule)
-> beaS (using A -> aS production rule)
-> beababe (using A -> babe production rule)
Round 3:
S -> SA (using S -> SA production rule)
-> beA (using A -> be production rule)
-> beaS (using A -> aS production rule)
-> beababe (using A -> babe production rule)
-> ababebabe (using S -> be production rule)
Round 4:
S -> SA (using S -> SA production rule)
-> beA (using A -> be production rule)
-> beaS (using A -> aS production rule)
-> beababe (using A -> babe production rule)
-> ababebabe (using S -> be production rule)
-> ababeababe (using S -> be production rule)
The leftmost derivation found by the brute force parsing algorithm for the input string "w = abab" is:
S -> SA -> beA -> beaS -> beababe -> ababebabe -> ababeababe
Note that we eliminate derivations from the next round if the prefix of the input string doesn't match the sentential form, if the sentential form has more than four symbols, or if the sentential form consists of all terminals and doesn't match the input string.

fun(n):
if(n<=1): return n
else: return 8*fun(n/2)
The asymptotic running time for computing fun() is O(log n).
The lowest bound for computing fun() is O(log n).
The time complexity of the given function `fun(n)` can be determined as follows:
Since the function `fun(n)` operates on half of the input each time it is called, we can assume that it would be called log n times as the input size reduces by half at each step.
In addition, the function takes O(1) time to complete the calculation once the function has been called.
The recursion tree diagram given below shows the number of nodes and the runtime per level, which is O(1) for each node.
The height of the recursion tree diagram is log n.
The total time complexity for computing `fun(n)` is the product of the number of nodes at each level and the runtime per node, which is O(1).
T(n) = Number of nodes * Runtime per node
= 1 + 2 + 4 + ... + 2^logn
= (2^logn+1 - 1)/(2-1)
= 2^(logn+1) - 1

Q3: 60 using binary search?
Q4: 60 using linear search?
Q5: Which search method is faster to find 0?
Q1:
In the given list, the first number is 0, so we don't need to do any searching as the first element in the list is already 0. So, 0 can be found using binary search in just one iteration.
Q2:
A linear search is a sequential search method that scans each item in the list, one at a time, until the target value is found. In the given list, 0 is the first element, so it can be found in just one iteration.
Q3:
Binary search is done on a sorted list or array. In the given list, the 60 can be found using binary search in three iterations. The list is first divided into two halves, and 60 is in the right half. The right half is then divided into two halves, and 60 is found in the left half.
Q4:
Since the given list is sorted, using linear search will take much longer to find 60. We would need to iterate through all of the elements in the list to find the value of 60.
Q5:

Given a number A, which equals 1,048,576. Please find another number B so that the GCD (Greatest Common Divisor) of A and B is 1,024.
This question has multiple correct answers, and you just need to give one. Please make sure you do not give 1,024 as your answer (no points will be given if your answer is 1,024).
If you are sure you cannot get the right answer, you may describe how you attempted to solve this question. Your description won't earn you the full points, but it may earn some.
To find a number B such that the GCD of A and B is 1,024, we can use the fact that if we multiply A by any number coprime with 1,024 (i.e., having no common prime factors with 1,024), the GCD of the resulting number and A will still be 1,024.
One such number is B = 2 * A, which equals 2,097,152. The GCD of A = 1,048,576 and B = 2,097,152 is indeed 1,024.
Since A = 1,048,576 is a power of 2, multiplying it by 2 will not introduce any new prime factors other than 2. As 1,024 is also a power of 2, their GCD will remain 1,024.
By multiplying A = 1,048,576 by 2, we obtain B = 2,097,152, where the GCD of A and B is 1,024. This is one possible answer to the given question, satisfying the condition of finding a number B such that its GCD with A is 1,024.

To create an application that will build a directed graph, the user will be prompted for the graph elements using a loop. The user will provide the connectivity information (i.e., "whether edge exists between all combination of points", e.g., 2 to 4) stored in an N x N, 2-D array. Use the adjacency matrix representation described on pg. 393. The application will create the nodes and build the graph using information stored in the 2-D array (passed to "Graph" constructor).The adjacency matrix is a matrix with rows and columns representing vertices of a graph. The entries of the matrix are 1 or 0 representing whether there is an edge between the vertices. The application can be implemented in Java as follows: `import java. util.
Scanner; public class Graph { private int[][] adj Matrix; private int vertex Count; public Graph(int vertexCount) { this.vertexCount = vertex Count; adj Matrix = new int[vertex Count][vertex Count]; } public void addEdge(int i, int j) { adjMatrix[i][j] = 1; } public void remove Edge(int i, int j) { adj Matrix[i][j] = 0; } public boolean isEdge(int i, int j) { return adjMatrix[i][j] == 1; } public String to String() { StringBuilder sb = new StringBuilder(); for (int i = 0; i < vertex Count; i++) { for (int j = 0; j < vertex Count; j++) { sb.append(adjMatrix[i][j] + " "); } sb.append("\n"); } return sb. to String(); } public static void main(String[] args) { Scanner sc = new Scanner(System.in); System. out.println("Enter the number of vertices:"); int v = sc.nextInt(); Graph g = new Graph(v); System. out.println("Enter the connectivity information:"); for (int i = 0; i < v; i++) { for (int j = 0; j < v; j++) { g.addEdge(i, j, sc.nextInt()); } } System. out.println("The adjacency matrix is:"); System. out. println(g); }}```In this application, the adjacency matrix is stored in the adjMatrix 2-D array. The constructor of the Graph class takes an argument vertex Count, which is the number of vertices in the graph. The add Edge method is used to add an edge between two vertices. The remove Edge method is used to remove an edge between two vertices. The isEdge method is used to check whether there is an edge between two vertices. The to String method is used to convert the adjacency matrix to a string representation. In the main method, the user is prompted to enter the number of vertices and the connectivity information. The connectivity information is used to populate the adjacency matrix. Finally, the adjacency matrix is printed to the console.
