(20 points) Merge sort involves recursively splitting the array into 2 parts, sorting and finally merging them. A variant of merge sort is called 3-way merge sort where instead of splitting the array into 2 parts we split it into 3 parts. As shown in the MergeSort code, it recursively breaks down the arrays to subarrays of size half. Similarly, 3-way Merge sort breaks down the arrays to subarrays of size one third In this question, you need to implement the 3-way Merge sort algorithm (in function mergeSort 3_way) in a descending order. During the sorting, count the number of comparisons in each merge stage. (20 points) Merge sort involves recursively splitting the array into 2 parts, sorting and finally merging them.
