Data Structures: STACKS

Find the resulting stack from the picture below to find the Y value if Y = X.pop();

X.push(new Integer (4)); X.push(new Integer (3)); Integer y = x.pop(); X.push (new Integer (7)); X.push(new Integer (2)); X.push(new Integer (5)); X.push(new Integer (9)); Integer Y = X.pop(); x.push(new Integer (3)); X.push(new Integer (9))
