Implement a queue Q using two stacks S1 and S2 such that operations ENQUEUE(Q, X) and DEQUEUE(Q, Y), where Q is supposedly a queue and X is the element to be inserted into Q and Y the element deleted from Q, are worked upon by the stacks that operate together as a queue. Assume that the ADT operations of PUSH, POP and EMPTYSTACK are only available for the stacks. Demonstrate the working of your method on a list {a, b, c}, which is to be operated upon as a queue by the stacks S1 and S2.
