Data structures in python.

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.Cheat Sheet 4: Princeton.edu.
