Consider an unsorted array of n elements. Recall that the Heapsort Algorithm consists of two parts: first we run BUILD-MAX-HEAP to convert our input array into a max heap, and then we run MAX-HEAPIFY n times to generate the n elements of our sorted array. Demonstrate the Heapsort Algorithm on the input array [5, 2, 1, 7, 6, 3, 4]. Clearly show your steps.
