Draw an example using the five integers (12, 23, 1, 45, 9) of how a stack could be used to reverse the order (9, 45, 1, 23, 12) of these elements.
What will be an ideal response?
The five values would be pushed onto the stack in order, yielding (with the top of the stack on the left):
9 45 1 23 12
Then popping each value produces them in the reverse order to which they were first encountered.
