Hi, can anyone help me to solve this question?

I know the stack is the last in first out. However, I do not know how to draw a picture to show the process.

5) [4] Given the following contents of an array implementation of a stack, where 50 is at the top of the stack. 2 3 4 5 20 30 40 50 Show the contents of the stack and the location of top after doing the following stack.pop) stack.push (60); stack.push (70); stack.push (80); stack.pop stack.push (90) 0 2 3 4
