Problem:In this problem, we would like to re-implement a selection sort to sort an array of numbers withsome improvements.Selection Sort divides the input list into two parts: the sublist of elements already sorted and theunsorted sublist of elements remaining to be sorted.- find the smallest element in the unsorted sublist- swap this element with the leftmost unsorted element, it equivalents to move this elementfrom the unsorted sublist to the sorted one,- continue to proceed all elements in the unsorted sublist.Question 1: ▪ Propose a recursive algorithm (pseudo-code) for the above Selection Sort (combined withiteration if necessary). ▪ Implement the proposed pseudo-code using C/C++ ▪ Calculate the complexity of your program (Best scenario, Worst scenario, Average). Justifyyour answer.
Please, answer and provide an explenation.
Using Java, 1. Implement external sort: for sort phase use normal sort, for merge phase use two way merge to merge n sorted files (merge2way(n)), for array sort use heapsort. Also write merge(f1, f2, f3) to merge two sorted files f1 and f2 into f3.. Write mergenway(n) method and print execution time of both merges for initial input file over 10MB data. A sample input is as follow:Note:Fist input is max array size for sort 10 84 82 52 80 96 85 75 75 82 87 92 89 57 94 93 92 63 99 87 72 73 56 74 50 84 62 72 55 86 75 74 100 83 60 53 68 89 67 66 65 72 94 73 54 98 96 85 75 75 82 87 92 89

Explain the behavior of Quicksort Algorithm when the input array A [1: n] consists of n identical elements.
ALGORITHM Quicksort(A[l..r])//Sorts a subarray by quicksort//Input: Subarray of array A[0..n − 1], defined by its left and right// indices l and r//Output: Subarray A[l..r] sorted in nondecreasing order if l < r s = Partition(A[l..r]) //s is a split position Quicksort(A[l..s − 1]) Quicksort(A[s + 1..r]) The above code is the quicksort algorithm.Perform a time complexity analysis for quicksort. You need to explain 1) what makes a worst case, what makes a best case, 2) the time complexity for both the worst case and the best case, 3) how to avoid the worst case in practice.
