A Binary Heap is a Complete Binary Tree. A binary heap is typically represented as array. The representation is done as:
- The root element will be at Arr.
- Below table shows indexes of other nodes for the ith node, i.e., Arr[i]:
Arr[(i-1)/2] Returns the parent node Arr[(2*i)+1] Returns the left child node Arr[(2*i)+2] Returns the right child node

The traversal method use to achieve Array representation is Level Order
Binary Heap satisfies the Ordering Property.
The Ordering can be of two types:
1. Min Heap Property: The value of each node is greater then or
equal to the value of its parent, with the minimum value at the root.
2. Max Heap Property: The value of each node is less then or
equal to the value its parent, with the maximum value at the root.
