Applications of Heap Data Structure

Implementation of Heap Data Structure:-

Advantages of Heaps:

Priority Queues: Priority queues can be efficiently implemented using Binary Heap because it supports insert(), delete() and extractmax(), decreaseKey() operations in O(log N) time.
Binomial Heap and Fibonacci Heap are variations of Binary Heap. These variations perform union also in O(log N) time which is an O(N) operation in Binary Heap.
Order statistics: The Heap data structure can be used to efficiently find the kth smallest (or largest) element in an array. You can see this gfg article to know more about the kth smallest or largest element.
