In this assignment you will implement a map using a hash table, handling collisions via separate chaining and exploring the map's performance using hash table load factors. (The ratio λ = n/N is called the load factor of the hash table, where N is the hash table capacity, and n is the number of elements stored in it.) Class Entry Write a class Entry to represent entry pairs in the hash map. This will be a non-generic implementation. Specifically, Key is of type integer, while Value can be any type of your choice. Your class must include the following methods: . A constructor that generates a new Entry object using a random integer (key). The value component of the pair may be supplied as a parameter or it may be generated randomly, depending on your choice of the Value type. . An override for class Object's compression function public int hashCode (), using any of the strategies covered in section 10.2.1 (Hash Functions, page 411). Abstract Class AbsHashMap This abstract class models a hash table without providing any concrete representation of the underlying data structure of a table of "buckets." (See pages 410 and 417.) The class must include a constructor that accepts the initial capacity for the hash table as a parameter and uses the function h (k)= k mod N as the hash (compression) function. The class must include the following abstract methods: size() Returns the number of entries in the map isEmpty() Returns a Boolean indicating whether the map is empty get (k) Put (k, v) Returns the value v associated with key k, if such an entry exists; otherwise return null. if the map does not have an entry with key k, then adds entry (k,v) to it and returns null; else replaces with v the existing value of the entry with key equal to k and returns the old value. remove (k) Removes from the map the entry with key equal to k, and returns its value; if the map has no such entry, then it returns null. Class MyHashMap Write a concrete class named MyHashMap that implements AbsHashMap. The class must use separate chaining to resolve key collisions. You may use Java's ArrayList as the buckets to store the entries. For the purpose of output presentation in this assignment, equip the class to print the following information each time the method put (k, v) is invoked: the size of the table, the number of elements in the table after the method has finished processing (k, v) entry . · the number of keys that resulted in a collision . the number of items in the bucket storing v Additionally, each invocation of get (k), put (k, v), and remove (k) should print the time used to run the method. If any put (k, v) takes an excessive amount of time, handle this with a suitable exception. Class HashMapDriver This class should include the following static void methods: 1. void validate() must perform the following: a) Create a local Java.util ArrayList (say, data) of 50 random pairs. b) Create a MyHashMap object using 100 as the initial capacity (N) of the hash map. Heads-up: you should never use a non-prime hash table size in practice but do this for the purposes of this experiment. c) Add all 50 entries from the data array to the map, using the put (k, v) method, of course. d) Run get (k) on each of the 50 elements in data. c) Run remove (k) on the first 25 keys, followed by get (k) on each of the 50 keys. f) Ensure that your hash map functions correctly. 2. void experiment interpret() must perform the following: (a) Create a hash map of initial capacity 100 (b) Create a local Java.util ArrayList (say, data) of 150 random pairs. (c) For n E (25, 50, 75, 100, 125, 150) . Describe (by inspection or graphing) how the time to run put (k, v) increases as the load factor of the hash table increases and provide reason to justify your observation. If your put (k, v) method takes an excessive amount of time, describe why this is happening and why it happens at the value it happens at.

Scenario: For a health-care client, you are designing \& developing a platform that caters to comprehensive medical care where patient data will be hosted on client's cloud service provider. The platform allows patients to avail health services from doctors associated with one or more of registered hospitals, including online diagnostic services and home-delivery of medicines Question: Which of the following Pll collected by the platform is likely to be optional for providing medical services? Age Mobile number or email address Unique identity, such as National Identity information Medical prescription
Answers
The optional data collected by the platform for providing medical services is the patient's mobile number or email address.
The patient's age, unique identity information (such as national identity), and medical prescription are likely to be essential data for providing comprehensive medical care. Age is important for understanding the patient's medical history, determining appropriate treatments, and assessing any age-related risks or conditions. Unique identity information helps in verifying the patient's identity, ensuring accurate medical records, and preventing fraud or errors in treatment. Medical prescriptions are crucial for doctors to prescribe medications accurately, monitor medication history, and avoid any adverse drug interactions.
On the other hand, the patient's mobile number or email address may be considered optional because it primarily serves as a means of communication and convenience for the patient. While it can be useful for sending appointment reminders, test results, or other updates, it is not essential for delivering medical services. Patients who prefer not to share their contact information can still receive medical care through other means such as in-person consultations or alternative communication channels provided by the platform.

True False In the array-based implementation of the stack, the top of the stack is at index 0. 3. O True False
Answers
1- When you pop an empty stack in the text implementation of the stack ADT, the program crashes. Option A is the correct answer.
In the text implementation of the stack ADT, popping an empty stack means trying to remove an element from a stack that has no elements. Since there are no elements to remove, the program encounters an error or an exception, resulting in a crash. This happens because the pop operation expects an element to be present in the stack before it can be removed. Option A is the correct answer.
2- The statement "In the array-based implementation of the stack, the top of the stack is at index 0" is False because in the array-based implementation of the stack, the top of the stack is typically at the highest index of the underlying array, not at index 0.
This means that when elements are pushed onto the stack, they are added to the end of the array (highest index), and when elements are popped from the stack, they are removed from the same end of the array. The index 0 is usually reserved for the bottom or base of the stack.

Answers
Topological Ordering problem The Topological ordering problem refers to a graph-theoretic problem that requires a consistent ordering of vertices on a directed acyclic graph (DAG).
This order requires that all the vertices precede their respective successors within the graph. One critical application of the topological ordering problem is that it is useful in reducing the computational effort required to solve problems such as project scheduling, dependency resolution, and other topological sort related problems.
The Topological Ordering problem can be solved using Kahn's algorithm, which utilizes the Breadth-First Search (BFS) strategy. The algorithm initially identifies vertices with zero incoming edges and places them in a queue. The process continues by iterating through all the vertices in the queue, eliminating the processed vertices' outgoing edges.

Answers
The statement "PC is an effective way to preserve web evidence" is false. Preservation of web evidence requires specialized techniques and tools, and simply using a personal computer is not sufficient.
Preserving web evidence involves capturing and storing digital information from websites or online platforms that may be relevant in legal or investigative proceedings. This process requires careful consideration of various factors such as authenticity, integrity, and admissibility of the evidence.
A PC alone is not designed or equipped with the necessary capabilities to effectively preserve web evidence. Preserving web evidence typically involves specialized tools and techniques such as web archiving software, digital forensic tools, and network monitoring tools.
Web archiving software enables the capture and storage of web pages and online content in a way that maintains their integrity and authenticity. It allows for the retrieval of web pages even if they have been modified or removed from the live web. Digital forensic tools are used to extract and analyze digital artifacts from web browsers, network traffic, and storage devices, ensuring that the evidence is collected in a forensically sound manner.
Furthermore, preserving web evidence often requires adherence to legal and regulatory requirements. This includes maintaining a proper chain of custody, ensuring the preservation of metadata, and following established procedures for evidence handling and documentation. These considerations go beyond the capabilities of a standard PC and require specialized expertise and resources.
In conclusion, while a PC can be used as a tool for accessing and viewing web content, it is not an effective way to preserve web evidence. Proper preservation of web evidence requires the use of specialized techniques, tools, and expertise to ensure the integrity, authenticity, and admissibility of the evidence in legal or investigative proceedings.

Answers
Given function is f(t) = A for w/2 ≤ w/2 and f(t) = 0 for all of the values of 't' and f(μ) and AW(sin (πWμ)/(πWμ))The Fourier transform of a function f(t) is F(w).The Fourier transform is a method of changing a time-domain signal into a frequency-domain signal.
Suppose we have a function f(t) and its Fourier transform F(w), then the Fourier transform of another function g(t) is calculated as follows:G(w) = integral of g(t)e^(-jwt) dt, where the integral is taken from -infinity to +infinity.The Fourier transform of a signal is a complex number with a magnitude and a phase angle.The Fourier transform is a mathematical technique for converting a time-domain signal into a frequency-domain signal. It works by representing a signal as a sum of sine and cosine waves. To obtain the Fourier transform, follow the below steps:Given, f(t) = A for 0 ≤ t ≤ W and f(t) = 0 for all other values of t.i.e., f(t) = A.u(t) - A.u(t - W)where u(t) is the unit step function.
The Fourier transform of f(t) can be obtained as:F(w) = integral of f(t) e^(-jwt) dtwhere the integral is taken from -infinity to +infinity. Using Laplace transform, we can obtain the Fourier transform without integrating Fourier. The Laplace transform can be obtained using the formula,Laplace transform = Fourier transform of f(t) / s where s = σ + jωWe can obtain the Laplace transform of the given function using the following formula,Laplace transform = A/s - A.e^(-Ws)/swhere s = σ + jωThe Fourier transform of the function can be obtained from the Laplace transform using the formula,Fourier transform = Laplace transform / (jω)On substituting the value of the Laplace transform and simplifying, we getFourier transform = (AW sin (πwW/2))/(πwW/2)Hence, the Fourier transform of the given function is F(w) = (AW sin (πwW/2))/(πwW/2) without using the integration of Fourier.

SOC 1, SOC 2, and SOC 3 reports are all part of the Service Organization Control (SOC) reporting framework established by the American Institute of Certified Public Accountants (AICPA).
These reports are designed to provide assurance to users regarding the security, availability, processing integrity, confidentiality, and privacy of a service organization's systems and controls. While they share similarities, they have distinct differences in their focus, purpose, and audience.
1. SOC 1 Report:
SOC 1 reports, formerly known as SAS 70 reports, are designed to evaluate the internal controls over financial reporting (ICFR) of a service organization. These reports are primarily relevant to organizations that provide outsourced services that may impact the financial statements of their clients. SOC 1 reports are important for entities such as data centers, payroll processors, and trust companies. They focus on the effectiveness of controls related to financial reporting rather than IT controls.
2. SOC 2 Report:
SOC 2 reports are intended to assess the service organization's controls related to security, availability, processing integrity, confidentiality, and privacy (commonly referred to as the Trust Services Criteria). These reports are relevant for organizations that provide services with a strong focus on data security and privacy. SOC 2 reports provide an evaluation of the design and operating effectiveness of controls related to these criteria, providing assurance to clients and stakeholders regarding the security and privacy of their systems and data. SOC 2 reports can cover one or multiple Trust Services Criteria based on the organization's specific requirements. The five Trust Services Criteria are often referred to as the AICPA Trust Services Categories:
- Security: Protection against unauthorized access, both physical and logical.
- Availability: Ensuring that systems are available for operation and use as agreed upon.
- Processing Integrity: Ensuring that processing is complete, accurate, timely, and authorized.
- Confidentiality: Protection of confidential information from unauthorized disclosure.

Use a test to determine whether the output matches the expected average of 4.5. First do the calculation by hand, using R to find the critical value to compare to. Then perform the test in R and compare your results.
Answers
A computer program claims to generate random numbers.T-test is a statistical hypothesis test that evaluates the difference between two populations by comparing their means. It is a part of inferential statistics. The statistical significance of the test helps determine whether or not the null hypothesis should be rejected.
The null hypothesis is that there is no difference between the two groups. The alternative hypothesis is that there is a difference between the two groups. The t-test assumes that the data are normally distributed. t.test() is a built-in function in R that performs the t-test. The function takes two input variables, which are the two data sets being compared, and returns a p-value. The p-value indicates whether the null hypothesis should be rejected or not. In R, we use the t.test() function to conduct the t-test on the provided data to find out whether the output matches the expected average of 4.5. The one-sample t-test in R is used to compare the sample mean to a known population mean.
The null hypothesis is that the sample mean is equal to the population mean. The alternative hypothesis is that the sample mean is not equal to the population mean. T
o conduct a one-sample t-test in R, use the t.test() function with the following syntax: t.test(x, mu) where x is the data vector and mu is the population mean. In this case, we have the following data:
8 3 2 4 5 6 7 3 5 6 8 2 3 5 4 2 1 2 3 4 3 3 4 5 6 3 2 1 3 4 5 4 7 5 3 2 5 6 6 3 2 3 4 3 5 2 2 2 1 1 2 3 4 3 6 1 5 3 5 3 6 1 8 4 2 7 4 2 3 7x <- c(8, 3, 2, 4, 5, 6, 7, 3, 5, 6, 8, 2, 3, 5, 4, 2, 1, 2, 3, 4, 3, 3, 4, 5, 6, 3, 2, 1, 3, 4, 5, 4, 7, 5, 3, 2, 5, 6, 6, 3, 2, 3, 4, 3, 5, 2, 2, 2, 1, 1, 2, 3, 4, 3, 6, 1, 5, 3, 5, 3, 6, 1, 8, 4, 2, 7, 4, 2, 3, 7)
H0: µ = 4.5Ha: µ ≠ 4.5t.test(x, mu=4.5)The output will be:
One Sample t-test
data: x
t = -1.7496, df = 69, p-value = 0.08527
alternative hypothesis: true mean is not equal to 4.5
95 percent confidence interval:
3.85789 4.44211
sample estimates:
mean of x
4.15
The t-value is calculated by dividing the difference between the sample mean and the null hypothesis mean (4.5) by the standard error of the mean. The p-value is the probability of obtaining a t-value as extreme as the observed t-value, assuming the null hypothesis is true. In this case, the p-value is 0.08527, which is greater than 0.05 (assuming a 95% confidence level). Therefore, we cannot reject the null hypothesis, and we conclude that there is not enough evidence to suggest that the output does not match the expected average of 4.5.

The following function is intended to count the number of occurrences of a given substring within a string, including overlapping occurrences. For example, if the string is 'banana' and the substring is 'an' , the function should return a count of 2; if the substring is 'ana' , the function should also return a count of 2. If the substring is 'nn' , the function should return 0, since this substring does not occur in 'banana' def count_with_overlap (string, substring): 1_one = len (string) 1_two = len (substring) i = 0 count = 0 while i<1_one: s = string.find(substring) if s == i: count count + 1 z = string[i+1:] #slicing the string if z.find(substring) >= 0: #finding substrings in that sliced string. count count + 1 i = i + 1 return countHowever, the function above is not correct.
(a) Provide an example of arguments, of correct types, that makes this function return the wrong answer or that causes a runtime error. The arguments must be two strings.
(b) Explain the cause of the error that you have found, i.e., what is wrong with this function. Your answer must explain what is wrong with the function as given. Writing a new function is not an acceptable answer, regardless of whether it is correct or not.
Answers
The issues with the function include incorrect comparison, incorrect updating of variables, and improper slicing, which lead to incorrect results or potential runtime errors.
(a) An example of arguments that would cause the function to return the wrong answer or produce a runtime error is when the substring is an empty string.
For example, if we call the function with arguments `count_with_overlap("banana", "")`, the function will enter an infinite loop because the condition `while i<1_one` will never be false. This is because the length of an empty substring is zero, and `i` will never increment inside the loop.
(b) The main issue with the provided function is that it doesn't update the value of `i` correctly within the loop. The line `s = string.find(substring)` is intended to find the first occurrence of the substring starting from index `i` in the string.
However, the result of this operation is not used correctly. Instead of checking if `s` is equal to `i`, the condition `if s == i` should be `if s == -1` to check if the substring is not found. Additionally, the lines `count count + 1` should be `count = count + 1` or `count += 1` to update the value of the `count` variable.
Furthermore, the slicing operation `z = string[i+1:]` doesn't skip to the next possible occurrence of the substring correctly. It should be `z = string[i+1+i_two:]` to skip to the next position after the current occurrence of the substring. Finally, the line `i = i + 1` should be placed outside the `if` statement to ensure that `i` is incremented for every iteration of the loop.

Calculate how many disk I/O operations are required for linked allocation strategy to insert one block after the third block from the beginning of the list. There are 50 blocks and you must explain your reasoning.
Answers
Linked allocation is a dynamic method for file allocation. It involves a chain of pointers, where each pointer points to the next block of the file. It is one of the simplest methods and does not involve any external fragmentation.
In this case, the linked allocation strategy has 50 blocks. To insert one block after the third block from the beginning of the list, we need to traverse the chain until we reach the third block from the beginning, then we insert the new block.
Here are the steps we need to follow to calculate the number of disk I/O operations required:
Step 1: To insert the new block, we first need to read the block that comes after the third block from the beginning of the list. This requires one disk I/O operation.
Step 2: Once we have read the block, we can insert the new block after it. This operation does not require any disk I/O operation.
Step 3: After the new block is inserted, we need to update the pointers of the third block from the beginning of the list and the new block. This requires two disk I/O operations.
Step 4: Finally, we need to write the modified blocks to the disk. This requires two disk I/O operations (one for each block).
Therefore, the total number of disk I/O operations required for linked allocation strategy to insert one block after the third block from the beginning of the list is 6.

Simple calculator that performs sum subtraction, division and
multiplication by interacting with user
Answers
To create a simple calculator that performs sum, subtraction, division and multiplication using JavaScript, the first step is to prompt the user to enter the numbers and operator. After taking the input, the appropriate operation will be performed on the numbers entered by the user. Here's a sample code for a calculator that can perform these four basic mathematical operations:
```
let num1 = parseFloat(prompt("Enter first number: "));
let num2 = parseFloat(prompt("Enter second number: "));
let operator = prompt("Enter operator (+, -, *, /): ");
let result;
if (operator === "+") {
result = num1 + num2;
} else if (operator === "-") {
result = num1 - num2;
} else if (operator === "*") {
result = num1 * num2;
} else if (operator === "/") {
result = num1 / num2;
} else {
result = "Invalid operator!";
}
console.log("Result: " + result);
```
This code prompts the user to enter the first and second numbers, as well as the operator. The `parseFloat()` function is used to convert the input from a string to a number. Then, the appropriate mathematical operation is performed based on the operator entered by the user, and the result is displayed using `console.log()`.
Note that this is a very simple calculator that does not handle any errors or invalid inputs. It also does not have a user interface, as it is purely written in JavaScript. However, this can serve as a starting point for building a more advanced calculator.

II. Given two circular linked lists one ordered one unordered write a routine which will merge them into one ordered list. Do not create a third list in the process.
Answers
This routine can be achieved through a process of iteration and comparisons to determine the correct position of the nodes in the new ordered list.
Step-by-step solution:
1. First, define two circular linked lists, one ordered and one unordered. The unordered list can be created by linking nodes randomly while the ordered list can be created by linking nodes in ascending order.
2. Define a pointer to traverse each of the lists starting from the head node. Initialize these pointers to point to the head nodes of their respective lists.
3. Compare the values of the nodes pointed to by the two pointers. If the value of the node in the unordered list is less than the value of the node in the ordered list, insert the node in the unordered list into the ordered list at the correct position, and move the pointer in the unordered list to the next node.
4. If the value of the node in the unordered list is greater than or equal to the value of the node in the ordered list, move the pointer in the ordered list to the next node.
5. Repeat the above steps until all nodes in the unordered list have been inserted into the ordered list.
6. Once the unordered list has been completely merged into the ordered list, the resulting list will be the ordered list with the additional nodes from the unordered list inserted in the correct position.
7. This process can be achieved in O(n) time complexity, where n is the number of nodes in both lists.

Answers
```python
divisible_by_7_not_by_3 = [num for num in range(5, 68) if num % 7 == 0 and num % 3 != 0]
```
To create a list of numbers between 5 and 67 (inclusive) that are divisible by 7 but not divisible by 3, we can use list comprehension in Python. List comprehension allows us to create a new list based on certain conditions.
In the given code, we start with `range(5, 68)` to generate a sequence of numbers from 5 to 67 (inclusive). Then, we use the condition `num % 7 == 0` to check if the number is divisible by 7. Finally, we add another condition `num % 3 != 0` to ensure that the number is not divisible by 3. By combining these conditions with the `if` statement, we filter out the numbers that meet the criteria.
The resulting list will contain only the numbers that satisfy both conditions: divisible by 7 and not divisible by 3. The list comprehension iterates through the range of numbers and adds the qualifying numbers to the new list. This concise and efficient approach eliminates the need for explicit loops and conditional statements.
After executing the code, the variable `divisible_by_7_not_by_3` will hold the desired list of numbers meeting the specified criteria.

What does cardinality represent in an entity-relationship diagram? The maximum number of entity instances in a relationship The total number of primary keys in an entity The total number of attributes
Answers
In an entity-relationship diagram, cardinality represents the maximum number of entity instances in a relationship. Cardinality is an important concept in the entity-relationship model that helps define the relationships between entities.
In database design, cardinality is the property that describes the relationship between two entities.There are three types of cardinalities: one-to-one, one-to-many, and many-to-many. One-to-one cardinality describes a relationship where each entity instance is associated with exactly one instance of the other entity.
One-to-many cardinality represents a relationship where an entity instance is associated with one or more instances of another entity, but each instance of the other entity can be associated with only one instance of the first entity. Many-to-many cardinality is used when an entity instance can be associated with multiple instances of another entity, and vice versa.
