What is the result of performing a heap sort on an array?

Step 1: Start with an unsorted array that you want to sort.
Step 2: Build a max-heap from the array. This means rearranging the elements so that the largest element is at the top.
Step 3: Swap the largest element (the root of the max-heap) with the last element of the array.
Step 4: Reduce the size of the heap by removing the last element (which is now in its correct position).
Step 5: Heapify the root of the heap to maintain the max-heap property.
Step 6: Repeat steps 3 to 5 until all elements are sorted.
