Overview

Merge sort is a divide-and-conquer algorithm that sorts an input array as follows:

1. Divide: it divides the initial array into two roughly equal sub-arrays of n/2 elements each. If n is even, the array is equally split, if n is odd ...
2. Conquer: it calls itself recursively to sort the sub-arrays
3. Combine: it merges the two sorted sub-arrays to produce the sorted answer
