The pop operation should throw an exception if the stack is empty. What should the peek operation do if the stack is empty?
What will be an ideal response?
The peek operation should probably also throw an exception. The user code is expecting that both pop and
peek will return the object at the top of the stack. If neither operation can succeed due to their being no object at the top of the
stack, then both operations should throw an exception.
