MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The merge sort algorithm is one of the most efficient sorting algorithms available and it has a number of distinct advantages. As a refresher, the merge sort algorithm works by first dividing a data set into two parts, then sorting each part separately and finally merging them back together in order.

Detailed explanation-2: -Quicksort. Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well.

Detailed explanation-3: -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-4: -Merge sort generally performs fewer comparisons than quicksort both in the worst-case and on average. If performing a comparison is costly, merge sort will have the upper hand in terms of speed. Quicksort is generally believed to be faster in common real-life settings.

Detailed explanation-5: -Quick sort is the better suited for large data sets. [8]It is the fastest and efficient algorithm for large sets of data. But it is inefficient if the elements in the list are already sorted which results in the worst case time complexity of O(n2).
