- The question should be done in C++, please give explanation and running result. 1. For this question, we need to provide more information about where the mismatch of the text file is happening. Write a recursive function called list_mismatched_lines that takes 2 filenames as input arguments and displays to the screen all mismatched lines in those files. This function should use hashing techniques and shall not compare strings to detect mismatch. The signature of this function should be: void list_mismatched_lines(std::string file1, std::string file2); In file1.txt, it contains "My dear C++ class. I hope that you enjoy this assignment. " In file2.txt, it contains "My dear C++ class. I hope that you like this assignment. " Example: Running the following line of code, should print to the screen the mismatched lines only, from both files. list_mismatched_lines(file1, file2); The following output should be seen on the screen: file1.txt: I hope that you enjoy this assignment.file2.txt:…Write a recursive function, displayFiles, that expects a pathname as an argument.

- Inspect the code and in your own interpretation, describe the reason call to function ChangeIt_1(n) will not change x in main()? Inspect the code and in your own interpretation, describe the reason parameter n in ChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? Write a function called void swap with two parameters, which will receive the address of x and y as pointer. The function should swap the value of x and y only if x is larger than y. Print the value of x and y after the function call. Write a function called double getAverage(int *array, int SIZE), where it accept the array as pointer, and return the average of the array. Print the returned value from this function. Always use *array rather than subscript to access the array value.Answer the given question with a proper explanation and step-by-step solution. PYTHON PLS!!!!!!!!!!!! In this lab you are asked to complete the recursive function populateDirectory(directory_dict). The function is input a dictionary containing data about the directory file structure and is to be used to populate a MyDirectory object. You are supplied with the classes: MyDirectory and MyFile. Note that file names always have the letter 'f' in the name (e.g. f0.txt). Any other names denote directoriesYou should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted. Don’t forget to include descriptive comments in your Python code. Your submission will be assessed using the following Aspects. Does the submission include the is_divisible function from Section 6.4 of the textbook? Does the submission implement an is_power function that takes two arguments? Does the is_power function call is_divisible? Does the is_power function call itself recursively? Does the is_power function include code for the base case of the two arguments being equal? Does the is_power function include code for the base case of the second argument being "1"? Does the submission include correct output for the five test cases?
- Instruction: Answer question 4 (a,b & c) only (1) Create a C++ project for your assignment 3, with the name format prescribed in the Information section. Add a source file and name it SwapCount. In this file, write the C++ program that will perform the tasks specified in question 2.(2) Declare and implement a function called sortSwapCount that passes three parameters, the array, the size and the reference of proportion, and returns the count. The functiondeclaration is int sortSwapCount(int data[], int size, double& proportion) (i) The function sorts the integers in data[] in ascending order using the bubble sort method. The purpose is to count or determine the number of exchanges (swaps) made by the bubble sort algorithm. (ii) The expected number of sorting swaps (expectedSwapCount) is size * (size - 1) if the array was unsorted. Calculate the proportion of the array status by first converting (or casting) the integers, swapCount and expectedSwapCount into floating-point,…1. Inspect the code and in your own interpretation, describe the reason call to functionChangeIt_1(n) will not change x in main()? 2. Inspect the code and in your own interpretation, describe the reason parameter n inChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? 3. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 4. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.Write a c++ function that accepts an array of doubles and the array’s size as its only arguments. The function should use dynamic memory allocation to create a new array that is double the size of the argument array. The function should copy the contents of the argument array to the second half of the new array and initialize the first half of the new 0s. The function should return a pointer to the new array. So, if the original array contained 1 2 3 4, the new array should contain 0 0 0 0 1 2 3 4. So, if the original array contained 1 2 3 4, the new array should contain 0 0 0 0 1 2 3 4.
- 1. Write a C program to count Non-Armstrong numbers from m and n (including m and n also) using the concept of passing pointers to function. Pass addresses of m, n and count integers from the main () function to the user defined function: calculate () [Function is not returning any value], and display the count in the main () function. 2. Write a program which should consists of a user defined function “Task ()” [Function returns no value]. Pass 1D array to the function, along with number of elements of array and element to search. Function should implement linear search, and if the element is not found in the array, then insert that element at the end of array .Display the final array after insertion [After function is called] in the main () function.

A recursive function typically has two components: one that provides a means for the recursion to terminate by testing for a case, and one that expresses the problem as a recursive call for a slightly simpler problem than the original…Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counterclass is passed as a parameter, the countproperty of that instance should be incremented based on the number of recursive calls. The __str__ method should return the countproperty's value as a string. Please can you change the solution to this problem here, because this is wrong.
