Webheapify is the central operation in Heap Sort. In buildHeap, it is called ⌊ n /2⌋ −1 times, and during the actual sort it is called n −1 times, for a total of ⌊3* n /2⌋ −2 times. As you can see, it is a recursive operation that executes a fixed number of computations until the end of the heap is reached.
