Implement a stack S with two queues Q1 and Q2, allowing the queues to act as a stack as a whole to handle the operations PUSH (S, X) and POP(S, Y), where S is presumably a stack and X is the element to be added to S and Y is the element removed from S. Assume that ADT's ENQUEUE, DEQUEUE, and EMPTYQUEUE operations can only access queues. Show how your function functions on the set of items (a, b, and c) that the queues Q1 and Q2 will utilise as a stack.

Heap Sort

A Heap is a type of data structure that is built on trees. It's a binary tree that's virtually complete. Except for the very bottom level, all levels of the tree must be filled in a heap. The last (bottom) level should be filled from left to right. The heap data structure is used for the efficient implementation of priority queues.Heap can be of two types:

Implement a queue Q with two stacks S1 and S2, so that the stacks that operate together as a queue may perform the operations ENQUEUE(Q, X) and DEQUEUE(Q, Y), where Q appears to be a queue and X is the element to be inserted into Q and Y is the element to be removed from Q. Assume that the ADT operations PUSH, POP, and EMPTYSTACK are only available for stacks.Show how your technique works on a list a, b, c, which will be utilised as a queue by the stacks S1 and S2.
