Are you familiar with stacks?
A stack is a data structure that is accessed only by it's last element.
The simplest stack is made with an array and a "top" index.
When you start, you can set the top index to zero.
To add data to the stack, you "push" it on.
To push, you simply do this:
To get data from a stack, you pop it.
So what you do is push ten values, then pop them back. Try it.
