Detailed explanation-1: -Which of the following method is used for sorting in merge sort? Explanation: Merge sort algorithm divides the array into two halves and applies merge sort algorithm to each half individually after which the two sorted halves are merged together. Thus its method of sorting is called merging.
Detailed explanation-2: -What Is a Merge Sort Algorithm? Merge sort is one of the most efficient sorting algorithms. It is based on the divide-and-conquer strategy. Merge sort continuously cuts down a list into multiple sublists until each has only one item, then merges those sublists into a sorted list.
Detailed explanation-3: -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-4: -The merge only works with sorted lists. Thus you divide until you get one or two elements, which can be trivially sorted either by leaving it alone or with a swap. Then you do the merging which takes elements in sequence from one or the other list.
