4. Assume X = {3,4,6,9,8,7,16,15,20,19} is an array representation of a binary heap, such that each element in X represents a node on the heap. Delete one node from the heap. After the deletion, the root node of the tree representing the heap is node The left child of the root node is node and the right child of the root node is node . The right child of node 8 is node A Que

Consider the Queue ADT: Queue: enqueue(x) adds x to the back of the queue dequeue () removes element at the front of the queue size() returns number of elements in queue Select all options that allow for an efficient implementation based on the discussions from class. For any array implementation, you can assume the array is large enough so that making a larger one is not needed when pushing an item to the stack. You can assume that a linked list will have both a head and tail reference. Using an array with the front of the queue at the front of the array. Using an array with the front of the queue at the back of the array. Using a singly linked list with the front of the queue at the head of the list. Using a singly linked list with the front of the queue at the tail of the list. None of these choices allows for an efficient implementation of all methods.

Circular Lists - All One Problem! A linear list is being maintained circularly in an array c[0…n-1] with front, and rear set up as for circular queues. Draft a formula/algorithm in terms of front, rear, and n for the number of elements in the list. Write an algorithm to delete the k-th element in the list. Write an algorithm to insert an element y immediately after the k-th element. Calculate the time complexity of your algorithms for b) and c).
