Merge sort
Merge sort is a recursive divide-and-conquer algorithm that essentially divides a given list into two halves, sorts those halves, and merges them in order. The base case is to merge two lists of size 1 so, eventually, single elements are merged in order; the merge part is where most of the heavy lifting happens. ...
