General case: In-place heapification (bottom-up bubble down heapification) takes O(N) time (naive in-place heapification, or top-bottom bubble up heapification, takes ϴ(NlogN) time). After heapification, we simply remove from the max-heap. The runtime of heapsort is ϴ(N + (time to remove all items)).

Web26 de jun. de 2024 · Heap is a complete binary tree.
