What is a Binary Heap?

Binary Heap is a Binary tree that is complete. Except for the last level all its levels are strictly completely filled. A Binary Heap is either a Min Heap or a Max Heap and is suitable to be stored in an array. Binary Heap has many applications like implementations of the priority queue, Heap Sort, etc.

Binary Heap also satisfied the heap ordering property. The order can be 2 types.

Min Heap Property: The value of each node is greater than or equal to the values of its parent, with the minimum-value at the root.

Max Heap Property: The value of each node is lesser than or equal to the values of its parent, with the maximum-value at the root.
