See full list on programiz.com Heap sort is simple to implement, performs an O(n·lg(n)) in-place sort, but is not stable. The first loop, the Θ(n) “heapify” phase, puts the array into heap order. The second loop, the O(n·lg(n)) “sortdown” phase, repeatedly extracts the maximum and restores heap order. The sink function is written recursively for clarity.
