Question: Suppose you have a stack S containing n elements and a queue Q that is initially empty. Describe how you can use Q to scan

Suppose you have a stack S containing n elements and a queue Q that is initially empty. Describe how you can use Q to scan S to see if it contains a certain element x, with the additional constraint that your algorithm must return the elements back to S in their original order. You may only use S, Q, and a constant number of other primitive variables.
