MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Merge sort is similar to the quick sort algorithm as it uses the divide and conquer approach to sort the elements. It is one of the most popular and efficient sorting algorithm.

Detailed explanation-2: -Merge sort is a sorting algorithm that works by dividing an array into smaller subarrays, sorting each subarray, and then merging the sorted subarrays back together to form the final sorted array.

Detailed explanation-3: -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-4: -Instead of dividing the input array into two subarrays, 4-way mergesort divides the array into four subarrays (as equally-sized as possible), sorts them recursively, and then calls a 4-way merge function, which combines four sorted arrays into one sorted array. a.
