- 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…Quicksort has several optimization strategies that we discussed in class. Select a valid one from the list below. (could be more than one) Always divide the input exactly in half in the first step, then adjust afterwards. Use recursion for larger files of similar data ranges. Use merge sort for sub-partitions. Use insertion sort for small partitions.Create an insertion sort implementation that, by positioning the smallest item first, gets rid of the j>0 condition in the inner loop.To determine whether doing so is successful, use SortCompare. This method frequently avoids an index-out-of-bounds test; the component that makes this feasible is referred to as a sentinel.
- Write a program that implements a sorted list using dynamic allocated arrays. DataFile.txt contains the information of poker cards. C: clubs(lowest),D: diamonds, H: hearts, S:spades(highest) 2 (lowest), 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A No Joker cards Any C cards are lower than any D cards. DataFile Content(You can write the file specification into your program.): H4,C8,HJ,C9,D10,D5,DK,D2,S7,DJ,H3,H6,S10,HK,DQ,C2,CJ,C4,CQ,D8,C3,SA,S2,HQ,S8,C6,D9,S3,SQ ,C5,S4,H5,SJ,D3,H8,CK,S6,D7,S9,H2,CA,C7,H7,DA,D4,H9,D6,HA,H10,S5,C10 H4, D5, HK, D2 H4, HK, SK C9,C10 For examples, DJ means J of Diamonds;H7 means 7 of hearts. Your job Create a list by dynamic allocated array and set the size to 20 Read the first 20 cards in the first line of the file, the put them one by one into the list by implementing and using putItem(). The list must be kept sorted in ascending order. Then print out all the cards in the list in one line separating by commas. Then delete the cards indicated in the second…Write a program that sorts an array of random or sorted numbers using Radix sort algorithms, fill the array with a nearly ordered list. Construct your nearly ordered list by reversing elements 19 and 20 in the sorted random list. Count the number of comparisons and moves necessary to order this list. Run the program three times, once with an array of 100 items, once with an array of 500 items, and once with an array of 1000 items. For the first execution only (100 elements), Print the unsorted data followed by the sort data 10x10 matrixes (10 rows of 10 numbers each).implement merge-sort multithreadA is an array and p and q indexes of the array such as you gonna sort the sub-array A[p..r]. B is a sub-array which willbe populated by the sort.A call to p-merge-sort(A,p,r,B,s) sorts elements from A[p..r] and put them in B[s..s+r-p]
- C++ Implement Exercise 8-13 using single dimensional parallel arrays. Create a text file with following data to test your code. Read the following data from this text file: Johnson 85 83 77 91 76Aniston 80 90 95 93 48Cooper 78 81 11 90 73Gupta 92 83 30 69 87Blair 23 45 96 38 59Clark 60 85 45 39 67Kennedy 77 31 52 74 83Bronson 93 94 89 77 97Sunny 79 85 28 93 82Smith 85 72 49 75 63 Using the data above your output should be: (image below) 8-13: Write a program to calculate students’ average test scores and their grades. You may assume the following input data: Johnson 85 83 77 91 76Aniston 80 90 95 93 48Cooper 78 81 11 90 73Gupta 92 83 30 69 87Blair 23 45 96 38 59Clark 60 85 45 39 67Kennedy 77 31 52 74 83Bronson 93 94 89 77 97Sunny 79 85 28 93 82Smith 85 72 49 75 63 Use three arrays: a one-dimensional array to store the students’ names, a (parallel) two-dimensional array to store the test scores, and a parallel one-dimensional array to store grades. Your program must contain at…implement a parametrized version of mergesort that will allow us to choose how many parts the input array will be divided into.This method will take an integer array and integer K as inputs and produce one integer array as output. It will sort the input array by dividing it into K parts, recursively sorting those parts, and using the mergeAll method to merge the K sorted arrays into one sorted array. Implement the mergesortK method public static int[] mergesortK(int[] arr, int k) { return new int[] {-1}; } *must be done in this format and in java pleaseimplement QuickSort of ints that sorts the numbers in the non-decreasing order. Implement the rearrange function using QuickSort ( such that the pivot is set on the extreme left and the rearrangement is carried on on two pointers) using the O(n) time algorithmThe function gets as input an array, and index of the pivot.The function rearranges the array, and returns the index of the pivot after the rearrangement. int rearrange(int* A, int n, int pivot_index); Implement the QuickSort algorithm. - For n<=2 the algorithm just sorts the (small) array (smaller number first). - For n>=3 the algorithm uses the rearrange function with the pivot chosen to be the median of A[0], A[n/2], A[n-1]. void quick_sort(int* A, int n);
- Write a program that discovers all anagrams of all words listed in an input file that stores the entries in a large dictionary. An anagram of a word is a rearrangement of its letters into a new legal word. For example, the anagrams of “share” include “shear”, “hears”, and “hares”. Assume that you have a file available to you that lists many words, one per line. Your program should first read in the dictionary file and sort it, but instead of sorting in alphabetical order it should sort according to each word's canonical form. The canonical form of a word contains the same letters as the original, but in sorted order. Thus, the canonical form of “computer” is “cemoprtu”, and the canonical form of “program” is “agmoprr”. When your dictionary file is sorted, the word “program” would be placed before the word “computer”, because its canonical form comes first in alphabetical order. Write code to retrieve a word's canonical form and a Comparator that compares words by using their canonical…An “inverted file” is a critical data structure for implementing applications like the index of a book, or a web search engine. Given a document D (which can be viewed as an unordered, numbered list of words), an inverted file is an ordered list of words L such that for each word W in L, we store the indices of the places in D where W appears. Write a C# program (from scratch please, written by yourself (ask instructor if you are stuck), not borrowed from any other sources) that reads in a list of words separated by spaces from a text file, then uses an efficient O(N) algorithm to create the inverted file index (hint: consider the topic of this chapter, consider using a Dictionary/hashtable to help you), and writes this index out to another file or prints it to the screen. Each line of the output file should start with the next word (the words should be listed in alphabetical order, and this sorting does not have to be part of the O(N) runtime complexity, e.g. you can use regular…Make a Java programme that first generates a collection of five-digit integers at random, then sorts those integers using three different methods: bubble sort, merge sort, and radix sort.For each sort, your application will show a progress indicator so you can see how quickly it is processing each one. To achieve the best outcomes, you might need to alter the size of your list of integers.
