Solve the problem by implementing the whole class with main() function and demonstrate that your Java code can pass several appropriate test cases successfully in your main() function
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.
