7.5.3.4 Heap SortFrom discussion on heap trees, it is evident that the root of a maxHeap contains
the largest value. When the root of the max heap is deleted, we get the largest element of the heap.
The remaining elements are put to reheap operation and we get a new heap. If the two operations
delete and reheap operation is repeated till the heap becomes empty and the deleted elements stored
in the order of their removal, then we get a sorted list of elements in descending order as shown in
Figure 7.35.
