Insertion sort is a simple sorting algorithm that builds the final sorted array one item at a time. In each iteration, insertion sort inserts an element into an already sorted list (on left). The position where the item will be inserted is found through linear search. You decided to improve insertion sort by using binary search to find the position p where the new insertion should take place. Algorithm BinarylnsertionSort Input/output: takes an integer array a = {a[0], ..., a[n - 1]} of size n begin BinarylnsertionSort for i =1 to n val = a[i] p= BinarySearch(a, val, 0, i – 1) for j = i-1 to p alj + 1]= a[] %3D end for a[p] = val i=i+1 end for end BinarylnsertionSort Here, val = a[i] is the current value to be inserted at each step i into the already sorted part a[0], . . , a[i - 1] of the array a. The binary search along that part returns the position p where the val will be inserted. After finding p, the data values in the subsequent positions j = | - 1, . . . , p are sequentially moved one position up to i, . .. , p+1 so that the value val can be inserted into the proper position p.

Double Insertion Sort is a variation on Insertion Sort that works from the middle of the array out. At each iteration, some middle portion of the array is sorted. On the next iteration, take the two adjacent elements to the sorted portion of the array. If they are out of order with respect to each other, then swap them. Now, push the left element toward the right in the array so long as it is greater than the element to its right. And push the right element toward the left in the array so long as it is less than the element to its left. The algorithm begins by processing the middle two elements of the array if the array is even. If the array is odd, then skip processing the middle item and begin with processing the elements to its immediate left and right. Implement Double Insertion Sort, being careful to properly handle both when the array is odd and when it is even. By using java, Implement the Double Insertion sort algorithm on a randomly generated list of N integer numbers. Your…

Multiply left and right array sum. Basic Accuracy: 54.29% Submissions: 12630 Points: 1 Pitsy needs help in the given task by her teacher. The task is to divide a array into two sub array (left and right) containing n/2 elements each and do the sum of the subarrays and then multiply both the subarrays. Example 1: â€
Let A = [5,20,55,45,30,24,8,16,32,25] . Apply Bubble Sort algorithm for the array A. Write the elements of the array at each iteration/pass.
In Bubble sorting works by comparing neighbours in the array and exchanging them if necessary to put the largest of the pair first. O True O Skip O False
Assume that we have a sorted list in an array: Index: 0 1 2 3 4 5 6 7 8 9 10 11 numbers: 12 15 17 19 22 26 28 30 32 34 36 38 we want to use the binary search algorithm to find the value 19 in the list. What would be the indexes of the array that the binary search would check to find the value 19 the indexes and not the actual numbers in the list otherwise
Exercise 1:In this problem, we would like to implement a variation of the Bubble Sort algorithm. The algorithm differs from a bubble sort in that it sorts in both directions on each pass through the list. The algorithm is illustrated as in the following figure: For the first step, we perform bubble sort from the index 1 to n (n is thenumber of elements in the array). The next step, we perform a reserved bubble sort from the index n to 1. The process is repeated until all the array is sorted. Propose a pseudo-code to complete the Bubble Sort algorithm. Implement and test this algorithm in C/C++. Analyze and compute the complexity of this algorithm in the best, average and worst scenarios.Exercise 2:Re-implement Exercise 1 using a linear data structure: List, Stack, Queue. Justify your choice of data structure.
: In searching an element in an array, linear search can be used, even though simple to implement, but not efficient, with only O(n) time complexity. Assuming the array is already in sorted order, modify the search function below, using a better algorithm, so the average time complexity for the search function is O(log n). include <iostream> using namespace std; int search(int al), int s, int v) { 1/ Modify below codes. for (int i = 0; i <s; i++) { if (a[i] = v) return i; return -1; int main() { int intArray:10] = { 5, 7, 8, 9, 10, 12, 13, 15, 20, 34); // Search for element '12' in 10-elements integer array. cout << search(intArray, 10, 12); // '5' will be printed out. // Search for element '35' in 10-elements integer array. cout << search(intArray, 10, 35); // '-1' will be printed out. // Index '-l' means that the element is not found. return 0;
