Question

Show the contents of two initially empty stacks after each of the following statements execute.

Notes:

Please show your work.

Assume a, b, g, and m are objects.

Your answer should show the contents of two stacks eight times- after each of the eight statements listed.

If you are writing the contents of your stack horizontally, use the left as the bottom and right as the top of your stack.

stack1.push(a)

stack1.push(b)

stack2.push(g)

stack2.push(m)

stack2.push(stack2.peek())

stack2.push(stack1.pop())

stack2.push(stack1.peek())

stack1.pop()

Explanation / Answer

stack1.push(a) => stack1 -> [a] => stack2 -> [] stack1.push(b) => stack1 -> [a, b] => stack2 -> [] stack2.push(g) => stack1 -> [a, b] => stack2 -> [g] stack2.push(m) => stack1 -> [a, b] => stack2 -> [g, m] stack2.push(stack2.peek()) => stack1 -> [a, b] => stack2 -> [g, m, m] stack2.push(stack1.pop()) => stack1 -> [a] => stack2 -> [g, m, m, b] stack2.push(stack1.peek()) => stack1 -> [a] => stack2 -> [g, m, m, b, a] stack1.pop() => stack1 -> [] => stack2 -> [g, m, m, b, a]
