Heapsort is an in-place sorting algorithm that uses a heap data structure. It works in two steps: 1. It uses the BuildHeap() function to convert the input array into a heap in O(n) time. 2. It then repeatedly extracts the maximum element from the heap, exchanges it with the last element, and sifts it down to maintain the heap property. This is done n-1 times to sort the entire array in O(n log n) time. The heap data structure can also be used to implement a priority queue, which supports operations like In
