In an array-based implementation of a List, why does the add operation take O(n) time in the average case? Select one: a. The time it takes to shift entries over to make room in the array depends on the number of entries in the List b. The time to copy the current entries into a newly allocated, larger array depends on the number of entries in the List c. The time to access the position in the array to add the new entry depends on the number of entries in the List d. The time to access the position in the array to add the new entry depends on the capacity of the array

The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
/** * Finds array t as a subsequence of arr and returns a list of the indices where * each element of t was first found. For example, given the array * <p> * arr = [65, 42, 137, 12, 42, 42, 17, 8, 99] * <p> * and t = [137, 42, 8] * <p> * the method should return the array of indices [2, 4, 7]. * <p> * If t is not a subsequence of arr, the method returns an empty array. * * @param arr source array * @param t target array to find in arr * @return list of indices where t was found, or an empty list */ public static int[] findSubsequence(int[] arr, int[] t) { }
An array with any number of elements is said to be repeating if any two or more of the elements are appearing in sequential an indexes after each other.Write a C++ function that accepts an integer array and returns 1 or “Repeating” if it is a repeating array, otherwise it returns 0 or “Not Repeating”. For Instance:2, 3, 5, 6, 7, 7, 7, 6, 8, 10 - Repeating2, 3, 4, 6, 4, 6, 4, 7, 8, 9 - Not repeating
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
Write an algorithmic faster version of this code. So the version that copies values from the first sorted half to a temp array then merges the values from the temp arr and the second sorted half into the original arr. public static <T extends Comparable<T>> void MergeSorting(T[] arr) {T[] tep = (T[]) new Comparable[arr.length];MergeSorting(arr, tep, 0, arr.length - 1);}//Recursive helper method for the merge sort algorithm.//arr The array to sort//tep Temporary array for merge operation//start Index of the left end of the region to sort //end Index of the right end of the region to sort. private static <T extends Comparable<T>> void mergeSort(T[] arr, T[] tep, int start,int end) {if (start >= end) {return;}int middle = (left + right) / 2;MergeSorting(arr, tep, start, middle); // first halfMergeSorting(arr, tep, middle + 1, end); //second halfMerge(arr, tep, start, middle, end);}private static <T extends Comparable<T>> void Merge(T[] arr, T[] tep,…

implement 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);
: 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.
Given two arrays A and B of equal size N, the task is to find a vector containing only those elements which belong to exactly one array - either A or B - but not both. That is, if some element x appears in both A and B it should not be included in the output vector. Complete the implementation of "getVector(vector<ll>A, vector<ll>B, int N)" function. Example: Input: 1 3 5 7 1 3 2 4 6 7 8 Output: 3 5 1 3 2 4 6 8 The driver codes are attached in the images below. DO NOT CHANGE THE PROVIDED DRIVER CODES AT ALL, LEAVE THEM EXACTLY THE SAME. ONLY ADD CODE TO THE "getVector(vector<ll>A, vector<ll>B, int N)" FUNCTION
Write a program in C or Java to delete an element at desired position from an array.Test Data :Input the size of array : 5Input 5 elements in the array in ascending order:element - 0 : 1element - 1 : 2element - 2 : 3element - 3 : 4element - 4 : 5Input the position where to delete: 3Expected Output :The new list is : 1 2 4 5
Code only_Given an unsorted array A of size N that contains only positive integers, find a continuous sub-array that adds to a given number S and return the left and right index(1-based indexing) of that subarray. In case of multiple subarrays, return the subarray indexes which come first on moving from left to right. Note:- You have to return an ArrayList consisting of two elements left and right. In case no such subarray exists return an array consisting of element -1..
Write a program that reads an array A of N elements containing only 0's and 1's. Your program should find the position of a 0 and replace it with a 1 to get the longest continuous sequence of 1's. Let this position of 0 be called P. Print P if such a 0 exists and print -1 if the original array A contains only 1's. Assume the array indexing starts from 0.
