So in level j, the total number of operation is j×2ʰ⁻ʲ. So the total running time for building the heap is proportional to: If we factor out the 2ʰ term, then we get:

Web19. aug 2024 · The heapsort algorithm consists of two phases: In the first phase, the array to be sorted is converted into a max heap. And in the second phase, the largest element (i.e., the one at the tree root) is removed, and a new max heap is created from the remaining elements. The following sections explain the two phases in detail using an example: Webtop-down: [adjective] controlled, directed, or instituted from the top level.
