Witryna11 kwi 2024 · Merge Sort is considered to be one of the fastest sorting algorithms, it is a bit more complex than Selection and Bubble Sort but its more efficient. The idea of Merge Sort is to divide the data-set into smaller data-sets, sort those smaller data-sets and then join them (merge them) together.

WitrynaMost of the steps in merge sort are simple. You can check for the base case easily. Finding the midpoint q q q q in the divide step is also really easy.
