We can analyze the cost of Heapsort by examining sub-functions of Max-Heapify and Build-Max-Heap. The cost of Max-Heapify is O(lgn).Comparing a node and its two children nodes costs Θ(1), and in the worst case, we recurse ⌊log₂n⌋ times to the bottom. Alternatively, the cost of Max-Heapify can be …

Prerequisite: Heap sort using min heap. Algorithm : Build a min heap from the input data. At this point, the smallest item is stored at the root of the heap. Replace it with the last item of the heap followed by reducing the size of heap by 1. Finally, heapify the root of tree. Repeat above steps while size of heap is greater than 1.
