Heaps
Heap is a binary tree having the properties:
Tree is complete or nearly complete.
Each node in a heap satisfies the heap condition, which states that
Key value in each node is greater than or equal to the key values

quick-sort is undoubtedly the most popular sorting
algorithm, and for good reason:
In the majority of situations, its the fastest, operating
in O(N*logN) time.
