A d-ary heap is like a binary heap, but each non-leaf node has at most d children instead of 2 , and the data structure is stored on a complete d-ary tree. a. How to implement a d-ary heap with n nodes in an array with at least n spots? (You want to answer these following questions: Where do we put each element into the array? How to find the parent of a node? And how to find the ith child of a node, for i=1 to d ?) b. How to MAX-HEAPIFY (A,i) in a d-ary max-heap? Analyze its time complexity in terms of d and n. c. How to INCREASE-KEY (A,i, key ) in a d-ary max-heap? Analyze its time complexity in terms of d and n
