X is a queue of integers with four elements and Y is a stack of integers with four elements. There are two integers A and B. [0] [1] [2] [3] X 2 A 10 Y [3] [2] B 20 [1] 5 [O] Draw the sequence diagrams of A, B, X and Y after each of the following operations: i) Y.push(X.serve()) ii) X.append (B+5) 111) B = Y.pop( * 2 iv) Y.push(A + B) v) if (X.serve()>Y.pop() X.append(Y.pop()
