In each plastic container of Pez, candy, the colors are stored in random order.
Your little brother Phil likes only the yellow ones, so he painstakingly takes out all the candies one by one, eats the yellow ones, and keeps the others in order, so that the can return them to the container in exactly the same order as before-minus the yellow candies, of course.
Write the algorithm to simulate this process.
(You may use any of the stack operations defined in the Stack ADT, but may not assume any knowledge of how the stack is implemented.)
