Solution

Merge sort

Merge sort is a divide-and-conquer algorithm that splits the input into two halves, sorts them separately, and then merges them. This process is repeated recursively, leading to a time complexity of O(n log n) in all cases (best, average, and worst), making it less dependent on the initial ordering of the input compared to the other sorting algorithms listed.
