Merge Sort is a stable sorting algorithm, meaning that two elements with equal values will retain their original order in the sorted output. This is accomplished through the use of comparisons.

Merge sort is efficient when sorting large datasets because of its time complexity.

One optimization for Merge Sort is to switch to insertion sort for small sub-arrays, as this can reduce the overhead of the merge process. This is known as Sort.

Merge sort is a sorting algorithm.

The merge sort algorithm is also an example of the -conquer algorithm paradigm.
