WebAug 19, 2024 · Besides, unlike Heapsort, Merge Sort is stable. Heapsort has an advantage over Merge Sort in that it does not require additional memory, while Merge Sort requires additional memory in the order of O(n). Summary. Heapsort is an efficient, unstable sorting algorithm with an average, best-case, and worst-case time complexity of O(n log n).
