Programming Part: Min-Max Heap [68pts] A min-max heap is a data structure that supports both deleteMin and deleteMax in O(log N) per operation. The structure is identical to a binary heap, but the heap-order property is that for any node, X, at even depth, the element stored at X is smaller than the parent but larger than the grandparent (where this makes sense), and for any node X at odd depth, the element stored at X is larger than the parent but smaller than the grandparent (see figure 1). 81 14 17 12 28 25 80 20 52 78 (31 42 31 59 16 (24) 79 63 18) 19 32 13 15 48 Figure 1: A min-max heap. Using an array to represent the min-max heap structure (in the same way as for min heap or max heap), implement the following operations. 1. buildHeap: Builds a min-max heap from a list of naturals read from standard input. 2. findMin and findMax : Returns the minimum (resp the maximum) element. 3. insertHeap: Inserts a new element into the min-max heap. 4. deleteMin and deleteMax: Deletes the minimum (resp the maximum) element.
