Detailed explanation-1: -Two-way merge is the process of merging two sorted arrays of size m and n into a single sorted array of size (m + n). Merge sort compares two arrays, each of size one, using a two-way merge. The sorted sequence is saved in a new two-dimensional array.
Detailed explanation-2: -Merge sort is one of the most efficient sorting algorithms. It works on the principle of Divide and Conquer based on the idea of breaking down a list into several sub-lists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list.
Detailed explanation-3: -Implementation of the merge sort algorithm is a three-step procedure. Divide, conquer, and combine.
Detailed explanation-4: -The time complexity of 2 way merge sort is n log2 n, of 3 way merge sort is n log3 n and of 4 way merge sort is n log4 n .
