What are final values in thestack S and in the Q after the following operations? Show contents ofboth S and Q at each step indicated by the line.Stack S;Queue Q;int x, y;S.push(10);S.push(20);S.push(S.pop()+S.pop();Q.enqueue(10);Q.enqueue(20);Q.enqueue(S.pop();S.push(Q.dequeue()+Q.dequeue());ExerciseSuppose we have an integer-valued stack S and a queue Q. Draw thecontents of both S and Q at each step indicated by the line. Be sure toidentify which end is the top of S and the front of Q.Stack S;Queue Q;S.push(3);S.push(2);S.push(1);Q.enqueue(3);Q.enqueue(2);Q.enqueue(1);int x = S.pop();Q.enqueue(x);x = Q.dequeue(();Q.enqueue(Q.dequeue());S.push(Q.peek());// peek() function reads the front of a queue without deleting it
