- Send FeedbackYou have been given two integer arrays/lists (ARR1 and ARR2) of size N and M, respectively. You need to print their intersection; An intersection for this problem can be defined when both the arrays/lists contain a particular value or to put it in other words, when there is a common value that exists in both the arrays/lists.Note :Input arrays/lists can contain duplicate elements.The intersection elements printed would be in the order they appear in the first sorted array/list (ARR1).Input format :The first line of input contains an integer 'N' representing the size of the first array/list.The second line contains 'N' single space separated integers representing the elements of the first the array/list.The third line contains an integer 'M' representing the size of the second array/list.The fourth line contains 'M' single space separated integers representing the elements of the second array/list.Output format :Print the intersection elements. Each element is printed in a…Develop and implement a version of mergesort that does not rearrange the array, but returns an int[] array perm such that perm[i] is the index of the i th smallest entry in the array.please do what is says Given a string representing an array/vector/linked-list (your choice, will use array for clarity moving forward) of integers both positive and negative, output all the negative values on the left-hand side of the array and all positive numbers on the right-hand side of the array while maintaining their relative positions. You must do this in linear time and linear space complexity or better, i.e. you cannot scan the entire list multiple times again and again to place the values in an new array. You MUST utilize methods related to QuickSort to receive credit for this problem. We will NOT accept iterative solutions. NOTE: Do NOT sort the array, the elements need to remain in their original relative order. Hint: take a look at the partition function in QuickSort. Case 1: Input 3: 1 -1 2 -2 3 -3 4 -4 5 -5 Output 3: -1 -2-3-4 -5 1 2 3 4 5 Case 2: Input 2: 14 9 -12 -13 -11 4 -4 3 3 9 Output 2: -12 -13 -11…
- 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…Implement a function GetMinimumCutSegments(int[] arr, int k) that takes in an array arr of positive integers and an integer k, and returns the minimum number of contiguous segments of the array that must be concatenated to form an array of size k. The function should return -1 if it is not possible to create an array of size k by concatenating contiguous segments of the input array. Example: Input: [1, 2, 3, 4], 6 Output: 2 Explanation: The minimum number of contiguous segments that must be concatenated to form an array of size 6 is 2. The two segments that can be concatenated are [1, 2] and [3, 4]. Input: [1, 2, 3, 4], 7 Output: -1 Explanation: It is not possible to create an array of size 7 by concatenating contiguous segments of the input array. Constraints: The input array arr will have at most length 100. The integer k will be at least 1 and at most 10^6. Can you write a C# function that solves this problem? public int GetMinimumCutSegments(int[] arr, int k) { // Your code…Implement substringList() that will produce the collection of words from the 1D array B that has substrings equivalent to the string key. The resulting collection should be stored in array C and this should contain only the unique set of words. The function returns the resulting total number of elements in array C. For your reference, a substring is a contiguous sequence of characters within a string. As an example, the strings “app”, “ppl”, “apple”, and “e” are among the substrings from the string “apple”. But, strings “ale” are “elppa” are not substrings from string “apple”. key = "or" array B = {"it's", "today", "now", "or", "forever", "today", "ACT"} array C should be {"or", "forever"} Rules: You can only use strcmp, strcat, and strcpy Maximize the use of loops (e.g., for) you can create local variables that can aid you
- You are given a 0-indexed integer array nums and a target element target. A target index is an index i such that nums [i] target. == Return a list of the target indices of nums after sorting nums in non-decreasing order. If there are no target indices, return an empty list. The returned list must be sorted in increasing order. vector targetIndices(vector& nums, int target) { //write your code here } Example 1: Input: nums = [1,2,5,2,3], target = 2 Output: [1,2] Explanation: After sorting, nums is [1,2,2,3,5]. The indices where nums[i] == 2 are 1 and 2.Given an integer array (data type: int) arr[10] with the initialized values for all its elements. For all the elements from arr[0] to arr[9], i.e., arr[0], arr[1], arr[2], ..., arr[8], arr[9], we call this array to be special, if it satisfies either one of two cases below: Case 1: arr[0] arr[2], arr[2] arr[4], .. Case 2: arr[0] > arr[1], arr[1] arr[3], arr[3] arr[1] for arr[0]. Part-(a). Write a program to determine whether this array is special or not. Part-(b). In this part, we can decrease any element by one each time. If the array is not special, determine the minimum number of decreases needed to change the array to be special. For example, if the array contains the following ten numbers "1, 2, 3, 4, 5, 6, 7, 8, 9, 10", it is not a special array. However, by decreasing "3 to 1", "5 to 3", "7 to 5" and "9 to 7", the array with these ten new numbers "1, 2, 1, 4, 3, 6, 5, 8, 7, 10" becomes special. The total number of decreases is 8 (= 2 + 2 +2 + 2), which is the minimum number…Using the reduce-and-conquer technique (specifically a fixed number of reduce and conquer, a fixed number of 1),Design and describe the algorithm that finds all subsets of a given n-element set A = {a1, a2, ………, an}, and also write it as pseudocode.You may think that the algorithm you will write takes a list / array as input (without element repetition) and returns a list / array of tuples as output.Each tuple in the returned list must represent a different subset of the input set.
- The general utility of numbering with collections The use of integer index values to access objects in a collection is something that we will see over and over again—not just with ArrayLists but also with several different types of collections. So it is important to understand what we have seen of this so far: that the index values start at zero; that the objects are numbered sequentially; and that there are usually no gaps in the index values of consecutive objects in the collection. Using integer values as indices also makes it very easy to express in program code expressions such as “the next item” and “the previous item” with respect to an item in the collection. If an item is at index p, then “the next” one will be at index (p+1) and “the previous” one is now at index (p–1). We can also map natural-language selections such as “the first three” to program-related terminology. For example, “the items at indices 0, 1, and 2” or “the last four” could be “the items at indices…: You are given an array-like data structure Listy which lacks a sizemethod. It does, however, have an elementAt ( i) method that returns the element at index i in 0( 1) time. If i is beyond the bounds of the data structure, it returns -1. (For this reason, the data structure only supports positive integers.) Given a Listy which contains sorted, positive integers,find the index at which an element x occurs. If x occurs multiple times, you may return any index.
