MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Quick sort is the fastest known comparison-based sorting algorithm when applied to large, unordered, sequences. It also has the advantage of being an in-place (or nearly in-place) sort.

Detailed explanation-2: -1. Which of the following sorting algorithms is the fastest? Explanation: Quick sort is the fastest known sorting algorithm because of its highly optimized inner loop. 2.

Detailed explanation-3: -If you’ve observed, the time complexity of Quicksort is O(n logn) in the best and average case scenarios and O(n^2) in the worst case. But since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

Detailed explanation-4: -Bubble Sort This sorting algorithm is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order.

Detailed explanation-5: -The real answer is that on average, for average data, quicksort is faster than merge sort (and heap sort, for that matter), and even though the worst case of quicksort is slower than merge sort’s, this worst case can be mitigated very easily (hence my answer). Quicksort is better in terms of memory as well.
