WebHeapSort is a comparison-based sorting technique where we first build Max Heap and then swap the root element with the last element (size times) and maintains the heap property each time to finally make it sorted. Examples: Input : 10 20 15 17 9 21 Output : 9 10 15 17 20 21 Input: 12 11 13 5 6 7 15 5 19 Output: 5 5 6 7 11 12 13 15 19 Web17 de jun. de 2024 · This upper bound, though correct, is not asymptotically tight. We can derive a tighter bound by observing that the running time of Heapify depends on the height of the tree ‘h’ (which is equal to lg (n), where n is a number of nodes) and the heights of most sub-trees are small. The height ’h’ increases as we move upwards along the tree. money heist hd
