A professor proposed a new sorting algorithm that works like merge-sort but does not require merge It works like the following Given an array a of n elements. Sort the first 3/4 of a: sort the last 3/4 of a: sort the first of 3/4 of a; return a as a sorted array The base case is an array of less than 8 elements, for which we will sort it using insertion sort. The pseudo code is shown below No merge.merge sort(a) f if (a.size0>8) No merge merge sort first 3/4 of a) No merge mexe sort(last 31/4 of a) No merge merge sort (fhrst 3/4 of a): ) else Insertion sort (a) a) Use a recurrent to describe the time complexity of the algorithm
