- Implement MERGE-SORT() algorithm that reads from a file named “inputHW02.txt” a list of double numbers (max =3,000,000 numbers), sorts those numbers and indicates time consumption. This programming question will address theadvantage of using iteration loops over recursive calls as well as using INSERTION-SORT() as a procedure in MERGESORT().Your program must perform the following actions:1. Opens the given file name and reads all double numbers. For simplicity, we assume this file only containsnumbers and nothing else.2. Implements the function INSERTION-SORT() that only sort an array of maximum 25 numbers. The idea is thatINSERTION-SORT() will be used as a sub-procedure to sort any sub-array when its size is small enough.3. Four versions of MERGE-SORT() namelya. MERGE-SORT-A(): Using recursive calls and NO INSERTION-SORT() as a sub-procedureb. MERGE-SORT-B(): Using ITERATIVE loops (i.e, NO recursion) and NO INSERTION-SORT() as a subprocedure.c. MERGE-SORT-C(): Using recursive calls…Create a recursive function in a file called ab_equality.py: def ab_equal(n, k, current): Print out all of the strings of a's and b's of length n so that the number of a's and b's are equal. For n = 2, there's ab and ba. For n = 3 there are no strings since they'd have to have 2 a's and 1 b, or 2 b's a 1 a so not equal. For n = 4, there will be 6 of these strings, and for n = 5, zero again. Hint: use k to track the difference between a's and b's. So for instance if your current is aaabb then k should be equal to either 1 or -1 (your choice depending). When you call the function, you should call it from your main or testing function with the length in the n parameter, 0 should be put into the k parameter, and then an empty string will be passed in for current.The task is to implement part of a linter program using python. Specifically, you must be able to scan for grouping symbols ( "()", "[]", "{}” ) and ensure that there are no hanging open symbols or stray closing symbols in the source file. The implementation must involve recursion in terms of scanning for the scope. If a different closing symbol is encountered or the end of file is reached, the error message "Line : missing closing symbol for "" should be displayed. For stray closing tags, the message "Line : stray closing symbol for "". Note: Do not use "stack" in your code.
- Here is the iterative implementation of binary search: For each call to binary_search below, indicate how many times the code inside the while loop will execute. animals = ["aardvark", "cat", "dog", "elephant", "panda"] 1. binary_search("elephant", animals) 2. binary_search("dog", animals) 3. binary_search("anteater", animals)Write the following function that merges two sorted lists into a new sorted list: void merge(const int list1[], int size1, const int list2[], int size2, int list3[]) Implement the function in a way that takes size1 + size2 comparisons. Write a test program that prompts the user to enter two sorted lists and display the merged list. Here is a sample run. Note that the first number in the input indicates the number of the elements in the list. This number is not part of the list. Assume the maximum list size is 80.What is the process to create an explicit bigO calculator for selection sort, insertion sort merge sort, and quicksort? Java. AP Computer Science A. One class. There is supposed to be four original lists, which is a random list of numbers from 1-10 with 10 items, these lists will be used by the four sorts. There should be the sorted list for those original lists from each sort method. There should be an amount of comparisons for each sort. Also there should be bigO information, the best case, average case, worst case, the nlog2n, the n^2, sorting 10 lists from the sort methods of n increasing. Thank you. What the output can look like:
- (B2). Implement a randomized Skip-List with operations Insert(), Delete() and Search(). Your program should read from the input file just like in (BI). Print out the skip-list using the format given below 16 16 71 91 2 16 71 89 91 2 10 15 16 31 71 86 89 91 96 27-10-15- 86 89 a 96Write a program that reads words from a filename, which is given as a string argument. It should return the words from the file in a list, sorted in reverse alphabetical order (case insensitive) . For instance, if the file has bell tea Zebra apple yellow Then the output should be ['Zebra', 'yellow', 'tea', 'bell', 'apple'] def reverse_sorted_words(filename): # YOUR CODE HERE raise NotImplementedError()Given the list of integers 2,-10, 12, 25, -32, 22, 56, 5, you are required to find the element whose rank is 4. This is the element whose index is 4, when the list is sorted in increasing order and indexed from 1 to 8. You are not allowed to sort the entire list; instead, you must use the PARTITION procedure discussed in class for QuickSort to partition the above list, determine which list contains the element you are looking for and recursively continue with this abbreviated list. Make a table with two columns: the first column enumerates the list in which the element lies and the second column states its rank in this list. Thus the first (and trivial) row entry would have the above list in the first column and 4 in the second column.
- Ask the user to enter a series of integers, and store these numbers into a linked list. The user can enter as many numbers as she like, so your program must keep asking for more until she enters -100 to signify she wants to stop. Please note that your program must store the number into a *linked list*, and not an array, because in theory, the user can enter unlimited number of integers, and all array has a fixed size. * Implement a C function to perform merge sort. This function takes the linked list above as the input, and sort it using the Merge Sort algorithm. You do have a choice here: You can either perform the merge sort directly on the linked list (more fun), or copy the numbers from the linked lists into an array first, and then sort the array (more familiar).In this programming exercise you will implement two functions. The first function will prompt the user for a file containing the number of vertices and entries of the adjacency matrix of a graph. It will return a two-dimensional list (a list of lists) containing the adjacency matrix. The second function will take as input the a two-dimensional list that represents the adjacency matrix of a graph, runs Prim's algorithm, and returns the list of edges in a minimal spanning tree and the total weight of the spanning tree.

The bubble-sort algorithm makes several passes through the list. On each pass, successive neighboring pairs are compared. If a pair is in decreasing order, its values are swapped; otherwise, the values remain unchanged. The technique is called a bubble sort or sinking sort because the smaller values gradually “bubble” their way to the top and the larger values “sink” to the bottom. Write a test program that reads in ten numbers, invokes the function, and displays the sorted numbers.
