Answer: Could be anything
Explanation: The pivot could be anything as All the elements at the left of any element is less than that element and all the elements on the right are greater than that element. Hence any element could be possibly pivot.

Modify the sorts (selection sort, insertion sort, bubble sort, quick sort, and merge sort) by adding code to each to tally the total number of comparisons and total execution time of each algorithm. Execute the sort algorithms against the same list, recording information for the total number of comparisons and total execution time for each algorithm. Try several different lists, including at least one that is already in sorted order. ---------------------------------------------------------------------------------------------------------------- /** * Sorting demonstrates sorting and searching on an...

Using C++, sort an array of 10,000 elements using the quick sort algorithm as follows: a. Sort the array using pivot as the middle element of the array. b. Sort the array using pivot as the median of the first, last, and middle elements of the array. c. Sort the array using pivot as the middle element of the array. However, when the size of any sublist reduces to less than 20, sort thesublis t using an insertion sort. d....

Selection Sort is a common algorithm to sort the elements of an array. First, it scans the elements of the array to find the smallest value and places it at index 0, thus creating a sorted “subarray” of size 1 that contains the smallest value. Then it scans the remaining unsorted values for the new smallest value and places it at index 1, creating a sorted subarray of size 2 that contains the 2 smallest values. It continues in this...

QUESTION 3 Suppose that you have been running an unknown sorting algorithm. Out of curiosity, you once stopped the algorithm when it was part-way done and examined the partially sorted array. You discovered that the last K elements of the array were sorted into ascending order, but the remainder of the array was not ordered in any obvious manner. Based on this, you guess that the sorting algorithm was (select all that apply): heapsort insertion sort mergesort quicksort Shell's sort...

The quick sort algorithm uses a ________ to divide the array into two pieces. Group of answer choices divider pivot mid-point key Which of the following statement(s) are true about quick sort? Group of answer choices It does not require additional memory that merge sort does. All of them In practice, it can be faster than merge sort. It can degrade into an O(n2) sort if the pivot-selection scheme is bad. Which sort does not use comparisons? Group of answer...
