WebApr 3, 2024 · Heapify: It is the process to rearrange the elements to maintain the property of heap data structure. It is done when a certain node creates an imbalance in the heap due to some operations on that node. It takes O (log N) to balance the tree. For max-heap, it balances in such a way that the maximum element is the root of that binary tree and. WebMar 20, 2024 · 1. make_heap () Function The std::make_heap () function is used to convert the given range in a container to a heap.
