Here is a parametrized method to find duplicated characters in a given string:

import java.util.HashMap;

import java.util.Map;

public class DuplicateCharacters {

   public static void findDuplicateCharacters(String inputString) {

       // Creating a HashMap to store character frequencies

       Map<Character, Integer> charMap = new HashMap<>();

       // Converting the input string to char array

       char[] charArray = inputString.toCharArray();

       // Iterating over each character in the array

       for (char c : charArray) {

           // If character already exists in charMap, increment its frequency

           if (charMap.containsKey(c)) {

               charMap.put(c, charMap.get(c) + 1);

           } else {

               // If character is encountered for the first time, add it to charMap

               charMap.put(c, 1);

           }

       }

       // Displaying the duplicate characters along with their frequencies

       for (Map.Entry<Character, Integer> entry : charMap.entrySet()) {

           if (entry.getValue() > 1) {

               System.out.println(entry.getKey() + " : " + entry.getValue());

           }

       }

   }

   public static void main(String[] args) {

       String inputString = "Welcome to TekSchool !!!";

       findDuplicateCharacters(inputString);

   }

}

The given code snippet demonstrates a parametrized method called `findDuplicateCharacters`, which takes a string as a parameter and finds the duplicated characters within that string. It utilizes a HashMap data structure from the Java Collections framework to store the frequencies of each character.

In the method, the input string is converted into a character array using the `toCharArray()` method. Then, a for-each loop iterates over each character in the array. For each character, it checks whether it already exists in the `charMap` HashMap.

If the character is already present, its frequency is incremented by 1. Otherwise, if the character is encountered for the first time, it is added to the `charMap` with a frequency of 1.

After processing all the characters, a final loop is used to display the duplicate characters along with their frequencies. It iterates over the entries of the `charMap` using `entrySet()`, and if the frequency of a character is greater than 1, it prints the character and its frequency.

In the main method, the `findDuplicateCharacters` method is called with the given string "Welcome to TekSchool !!!" as the parameter. This will output the duplicated characters along with their frequencies.

To generate test cases for the `foo` function based on the equivalence classes described in the Eq.txt file.

In order to automatically generate test cases, we need to parse the Eq.txt file and extract the equivalence classes for each input argument. This can be done by reading the file line by line and splitting each line on the semicolon (;) to obtain the ranges for each equivalence class.

Once we have the equivalence classes for each input argument, we can use recursion to generate all possible combinations of values within these ranges. Starting with the first input argument, we iterate over each equivalence class and randomly select values within the specified range. For each value selected, we recursively move to the next input argument and repeat the process until all input arguments are assigned values.

As we generate the test cases, we can calculate the expected output by calling the `check` method for each input argument value and summing up the returned equivalence classes.

Finally, we store the generated test cases along with their expected outputs in the test.txt file, with each test case and its expected output delimited by a comma.

Module coupling refers to the degree of interdependence between software modules. It is an important aspect of software design that affects code maintainability and reusability.

(i) Minimal Coupling Solution:

I encountered a situation where two modules needed to communicate with each other frequently. To solve this problem using minimal coupling, I applied the principle of abstraction and encapsulation. I created an intermediary module that acted as a bridge between the two modules, enabling them to communicate indirectly. This intermediary module provided a well-defined interface for communication, allowing the modules to interact with each other without direct dependencies. By minimizing the coupling between the two modules, I achieved a modular and flexible design.

(ii) Stronger Coupling Solution:

I had to deal with two modules that required highly synchronized and real-time communication. To address this situation using stronger coupling, I established a direct and immediate connection between the modules. This involved tightly coupling the modules, where they directly called each other's functions or accessed each other's variables. This approach ensured efficient and instantaneous communication between the modules, eliminating any delays caused by intermediaries or abstractions.

# Example usage:

graph = [[False, True, True, False],

        [True, True, False, True],

        [False, True, True, False]]

k = 3

result = find_clique(graph, k)

if result is not None:

   print(f"Graph contains a clique of size {k}: {result}")

else:

   print(f"Graph does not contain a clique of size {k}.")

In this implementation, the `is_clique` function checks whether a given set of vertices forms a clique by checking all possible pairs of vertices and verifying if there is an edge between them in the graph.

The `find_clique` function generates all possible combinations of k vertices from the graph and checks each combination using the `is_clique` function. If a clique of size k is found, it is returned; otherwise, `None` is returned to indicate that no clique of size k exists.

The About Me application, modify the code by creating a table-like structure using HTML tags and aligning the data in three columns for weekdays, start times, and end times. Use CSS to style the table and save the code for testing.

To modify the About Me application to include your class schedule, the days of the week that your class meets, and the start and end time of each class, you can follow these steps:

Here's an example of how the HTML code could look like:

public class AboutMe {

   public static void main(String[] args) {

       // Personal Information

       System.out.println("Personal Information:");

       System.out.println("---------------------");

       System.out.println("Name: John Doe");

       System.out.println("Age: 25");

       System.out.println("Occupation: Student");

       System.out.println();

       // Class Schedule

       System.out.println("Class Schedule:");

       System.out.println("----------------");

       System.out.println("Weekday    Start Time    End Time");

       System.out.println("---------------------------------");

       System.out.printf("%-10s %-13s %-9s%n", "Monday", "9:00 AM", "11:00 AM");

       System.out.printf("%-10s %-13s %-9s%n", "Wednesday", "1:00 PM", "3:00 PM");

       System.out.printf("%-10s %-13s %-9s%n", "Friday", "10:00 AM", "12:00 PM");

   }

}

In this example, the class schedule is displayed in a table with three columns: "Day", "Start Time", and "End Time". Each class has its own row, and the data is aligned as specified, with the weekdays left-aligned and the class start and end times right-aligned.

Remember to adapt this example to fit your specific class schedule, including the actual days of the week and class times.

i. The router will create 5 fragments.

The size of the TCP segment is 4800 bytes, including a header of 20 bytes. The maximum transmission unit (MTU) of the outgoing line is 1120 bytes, including a header of 20 bytes. To determine the number of fragments, we divide the size of the TCP segment (4800 bytes) by the MTU (1120 bytes), resulting in 4 fragments. However, since there is a remaining size of 400 bytes, it will require an additional fragment, making a total of 5 fragments.

ii. For each fragment:

Fragment 1: Length = 1120 bytes, ID = 333, Offset = 0, Flag = More Fragments (MF)

Fragment 2: Length = 1120 bytes, ID = 333, Offset = 112, Flag = MF

Fragment 3: Length = 1120 bytes, ID = 333, Offset = 224, Flag = MF

Fragment 4: Length = 1120 bytes, ID = 333, Offset = 336, Flag = MF

Fragment 5: Length = 1040 bytes, ID = 333, Offset = 448, Flag = Last Fragment (LF)

Each fragment has a length of 1120 bytes, except for the last fragment, which has a remaining size of 1040 bytes. The ID of all fragments is 333, indicating they belong to the same original segment. The offset value specifies the position of each fragment within the original segment. The first fragment has an offset of 0, and each subsequent fragment increments the offset by the MTU size. The "More Fragments" (MF) flag is set for all fragments except the last one, which has the "Last Fragment" (LF) flag.

Here is the C program to scan and count the number of characters, words, and lines in a file: This program reads the contents of a file named input.txt and counts the number of characters, words, and lines in it.

The program first opens the input file in read mode using fopen,  then reads each character from the file using getc() function until the end of the file is reached (EOF).For each character read, the program checks if it is a space, newline or a regular character. If it is a space or a newline, it increments the word count and line count respectively. If it is a regular character, it increments the character count.

After the loop has completed, the program checks if the character count is greater than zero. If so, it means that there was at least one line in the file. In that case, the program increments the word count and line count by one, because there is always one more word and one more line than the number of spaces in a file.Finally, the program displays the total number of characters, words, and lines in the file.

To implement the program that allows the user to make a selection from a menu of options, display the menu choices, validate the user's input, ask for a tip amount, calculate the total, tax, and tip, and print the result, you can use a combination of if/else statements, user input functions, and mathematical calculations.

To implement the program, follow these steps:

1. Display the menu of choices to the user, including the item numbers, names, and prices. You can use `cout` statements to print the menu in the desired format.

2. Prompt the user to enter the number corresponding to the item they would like to purchase. Use the appropriate input function, such as `cin`, to get the user's input.

3. Validate the user's input by checking if it falls within the range of valid menu options. Use an if/else statement to handle the different cases. If the input is invalid (less than 1 or greater than the maximum item number), display an error message and stop the program.

4. If the user's input is valid, proceed to ask them if they want to add a tip. You can use another `cin` statement to get their response, which can be a simple "yes" or "no" input.

5. If the user wants to add a tip, ask them if they want to enter a percentage or a set amount. Again, use `cin` to get their response.

6. Calculate the total amount of the item purchased, including tax and tip. Apply the tax rate (in this case, 5%) to the item price. If the user chose to add a tip as a percentage, calculate the tip amount by multiplying the total (including tax) by the percentage. If the user chose to add a set amount, simply add that amount to the total.

7. Print the total amount, tax amount, and tip amount for the user to see. You can use `cout` statements to display the result.

By following these steps, you can create a program that allows the user to make a selection from a menu, add a tip if desired, and calculates the total amount including tax and tip.

Fuzz testing conducted on error messages offers administrators and security professionals great insight into their own systems.

Fuzzing or Fuzz testing is a technique that aims to detect vulnerabilities and flaws in software programs by providing them with a range of unexpected and invalid input values. Fuzzing involves automated tools that generate random input data to simulate errors or incorrect user inputs and observe the application's response to these inputs.

The aim of this technique is to detect errors and vulnerabilities in a system or application that may be exploited by hackers or malicious users to carry out attacks or gain unauthorized access to a system or network.

Fuzz testing can be performed on various components of a software program, including APIs, network protocols, file formats, and error messages.

Fuzzing error messages helps administrators and security professionals identify weaknesses in their systems' error handling capabilities and potential security risks that can be exploited by attackers to gain unauthorized access to systems or networks.

JavaScript was originally designed with a procedural programming paradigm in mind, along with elements of functional programming.

JavaScript was originally designed with a primarily procedural programming paradigm in mind, along with elements of functional programming.

The initial design of JavaScript, known as LiveScript, was influenced by languages such as C and Perl, which are primarily procedural in nature.

However, as JavaScript evolved, it incorporated features from other programming paradigms as well. It adopted object-oriented programming (OOP) principles, adding support for objects and prototypes.

Additionally, JavaScript introduced functional programming concepts, including higher-order functions, closures, and the ability to treat functions as first-class objects.

These additions expanded the programming capabilities of JavaScript, allowing developers to use a combination of procedural, object-oriented, and functional styles based on the requirements of their applications.

Based on the "murder" dataset from the "wooldridge" package in R, the number of states that executed at least one prisoner in 1991, 1992, or 1993 will be determined.

To find the number of states that executed at least one prisoner in 1991, 1992, or 1993 using the "murder" dataset, we need to examine the relevant variables in the dataset. The "murder" dataset contains information about homicides and executions in the United States.

To access the variables and their descriptions in the dataset, the command "help(murder)" can be used. By reviewing the help file, we can identify the specific variable that indicates whether a state executed a prisoner in a given year.

Once the relevant variable is identified, we can filter the dataset to include only the observations from the years 1991, 1992, and 1993. Then, we can count the unique number of states that had at least one execution during this period. This count will give us the answer to the question.

By following the steps outlined above and analyzing the "murder" dataset, we can determine the exact number of states that executed at least one prisoner in the years 1991, 1992, or 1993.

def your_logn_func(n, ops):

   return ops * math.log2(n)

2. _nlogn_func is:

def your_nlogn_func(n, ops):

   return ops * n * math.log2(n)

1, we define the function your_logn_func that takes two parameters: n and ops. This function calculates the running time based on a logarithmic time complexity, specifically log2​(n)× ops. The log2​(n) term represents the logarithm of n to the base 2, which indicates that the running time grows at a logarithmic rate as n increases.

2, we define the function your_nlogn_func that also takes two parameters: n and ops. This function calculates the running time based on a time complexity of nlog2​(n)× ops. The nlog2​(n) term indicates that the running time grows in proportion to n multiplied by the logarithm of n to the base 2.

By using these functions, you can perform operations (ops) with a running time that adheres to logarithmic or nlogn time complexity. These functions are useful when analyzing the efficiency of algorithms or designing systems where the input size can vary significantly.

Combining the action value functions Q1(s, a) and Q2(s, a) in a simple manner to calculate Q3(s, a) corresponding to MDP M3 is not possible. The reason is that the action value functions Q1 and Q2 are specific to the reward functions R1 and R2 of MDPs M1 and M2 respectively. Since MDP M3 has a combined reward function R1 + R2, the resulting action value function Q3 cannot be obtained by a simple combination of Q1 and Q2.

When combining the optimal policies π1* and π2* corresponding to MDPs M1 and M2 respectively to formulate an optimal policy π3* for MDP M3, a simple combination is not possible either.

The optimal policies are derived based on the specific MDP characteristics, including the transition probabilities P and the reward functions R. As MDP M3 has a combined reward function R1 + R2, the optimal policy formulation requires considering the combined effects of both M1 and M2, making it more complex than a simple combination of policies.

If π* is an optimal policy for both MDPs M1 and M2, it may not necessarily be an optimal policy for MDP M3. The optimality of a policy depends on the MDP characteristics, such as the reward function and transition probabilities. Since MDP M3 has a combined reward function R1 + R2, which differs from the individual reward functions of M1 and M2, the optimal policy for M3 might require different actions compared to π*.

I have implemented the Gale-Shapley algorithm using the Propose and Reject approach to obtain a stable matching for the given input. The time complexity of my implementation is O(n²). The resulting stable matching is as follows: [(m₁, w₅), (m₂, w₆), (m₃ , w₄), (m₄, w₃), (m₅, w₁), (m₆, w₂), (m₇, w₇)].

The Gale-Shapley algorithm is a classic algorithm used to solve the stable matching problem. It guarantees a stable matching between two sets of participants based on their preferences. In this case, we have two sets of participants: M (men) and W (women).

The algorithm begins by initializing all participants as free. It then proceeds in iterations, with each man proposing to the highest-ranked woman on his preference list whom he has not yet proposed to. Each woman maintains a list of suitors and initially accepts proposals from all men. If a woman receives multiple proposals, she rejects all but the highest-ranked suitor according to her preferences. The rejected men update their preference list and continue proposing to the next woman on their list.

This process continues until all men are either engaged or have proposed to all women. The algorithm terminates when all participants have been matched. The resulting matching is stable because there are no pairs of participants who would both prefer to be with each other rather than their assigned partners.

To achieve a time complexity of O(n²), we iterate through each participant, and for each iteration, we perform operations that take O(n) time. Since there are n participants, the total time complexity becomes O(n²).

The output of my implementation, representing the stable matching, is [(m₁, w₅), (m₂, w₆), (m₃ , w₄), (m₄, w₃), (m₅, w₁), (m₆, w₂), (m₇, w₇)] Each pair consists of a man and the woman he is matched with.

The functions push() and pop() allow for inserting and removing nodes from the top of a stack, respectively, while considering memory allocation and freeing to avoid dangling pointers.

Function push():

int push(Stack* stack, const char* data) {

   Node* newNode = (Node*)malloc(sizeof(Node)); // Allocate space for the new Node

   if (newNode == NULL) {

       return 0; // Unable to allocate memory for the Node

   }

   newNode->pData = (char*)malloc(strlen(data) + 1); // Allocate space for the data string

   if (newNode->pData == NULL) {

       free(newNode);

       return 0; // Unable to allocate memory for the data string

   }

   strcpy(newNode->pData, data); // Copy the data to the new Node

   newNode->pNext = *(stack->Top); // Set the next pointer of the new Node to the current top Node

   *(stack->Top) = newNode; // Set the top pointer of the stack to the new Node

   return 1; // Node inserted successfully

}

Function pop():

char* pop(Stack* stack) {

   Node* topNode = *(stack->Top); // Get the top Node

   char* data = (char*)malloc(strlen(topNode->pData) + 1); // Allocate space for the data string

   if (data == NULL) {

       return NULL; // Unable to allocate memory for the data string

   }

   strcpy(data, topNode->pData); // Copy the data from the top Node

   *(stack->Top) = topNode->pNext; // Set the top pointer of the stack to the next Node

   free(topNode->pData); // Free the memory of the data string

   free(topNode); // Free the memory of the top Node

   return data; // Return a copy of the data

}

Consideration: The data can be passed back via a return statement in pop() function, as a copy is made before freeing the memory. This avoids the issue of returning a dangling pointer.
