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. WebOct 31, 2014 · A Binary Heap is a complete Binary Tree which is used to store data efficiently to get the max or min element based on its structure. A Binary Heap is either Min Heap or Max Heap.

WebMar 21, 2024 · Min Heap is used as a priority queue to get the minimum distance vertex from a set of not yet included vertices. The time complexity of operations like extract-min and decrease-key value is O (LogV) for Min Heap. Following are the detailed steps. Create a Min Heap of size V where V is the number of vertices in the given graph.

WebIn first Example, first we have to build Max Heap. So, we will start from 20 as child and check for its parent. Here 10 is smaller, so we will swap these two. Now, child 17 is greater than its parent 10. So, both will be swapped and order will be 20 17 15 10 9 21.
