Merge sort is a sorting algorithm.

Merge Sort is particularly useful for sorting linked lists, as it does not rely on random access to elements in the list. Instead, it uses a -like approach to merging the sub-lists.

The merge subroutine in Merge Sort is responsible for combining two sorted arrays into a single sorted array. This process is also known as .

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 a type of divide and conquer algorithm, meaning that it solves a problem by breaking it down into smaller sub-problems. This approach is also used by other algorithms such as sort.
