WebBuild max-heap. To build a max-heap from any tree, we can thus start heapifying each sub-tree from the bottom up and end up with a max-heap after the function is applied to all the elements including the root element. In the case of a complete tree, the first index of a non-leaf node is given by n/2 - 1. All other nodes after that are leaf ... WebNov 11, 2024 · Next let’s see how to build a heap from the input array.
