this problem, consider a non-standard sorting algorithm called the Slow Sort. Given an array A[1 : n] of n integers, the algorithm is as follows: Slow-Sort(A[1 : n]): 1. If n < 100, run merge sort (or selection sort or insertion sort) on A. 2. Otherwise, run Slow-Sort(A[1 : n −1]), Slow-Sort(A[2 : n]), and Slow-Sort(A[1 : n −1]) again. Question: Prove the correctness of Slow-Sort.
