Question

Given numStack: 74, 84, 38 (top is 74)

What is the stack after the following operations?
Push(numStack, 22)
Pop(numStack)
Push(numStack, 46)
Pop(numStack)

Answer 1

After the first operation, Push(numStack, 22), the stack becomes 74, 84, 38, 22, with 22 at the top.

After the second operation, Pop(numStack), the top element 22 is removed from the stack, so the stack becomes 74, 84, 38, with 38 at the top.

After the third operation, Push(numStack, 46), the stack becomes 74, 84, 38, 46, with 46 at the top.

After the fourth operation, Pop(numStack), the top element 46 is removed from the stack, so the stack becomes 74, 84, 38, with 38 at the top.

Therefore, the final stack after these operations is 74, 84, 38, with 38 at the top
