WebOrder: Use max-heapify to sort in asceding order, min-heapify to sort in descending order. Sorting: Building the heap with min-heapify does not sort your array; it only enforces the (weaker) min-heap property, that is A [parent (i)] <= A [i] for every node i other than the root. WebStep 1: Construct Max Heap from Given Array i.e. {10, 30, 5, 63, 22, 12, 56, 33} Initially, we must construct the max heap from the given array of elements. Now the given array will be changed and it is max-heap. Now the array looks like this: 63 56 33 12 30 22 10 5 Step 2: Delete the root node (63) & perform heapify operation.
