"WebHeaps can also be used in sorting an array. In the case of max-heaps, the maximum element is always present at the root of the heap. So we can use this property of the heap to sort an array. The idea is to pop out the maximum element i.e. root of the heap and then again heapify the array such that 2nd maximum element will be at the root of the ... " - Heaps and heapsort
