(a) Write a method in Java to sort a stack of n integer numbers, s, in increasing order. static Stack sort(Stack s) To implement this method you must use one more auxiliary stack and you should not make any assumptions about how the stack is implemented. The following are the only functions that should be used to write this program: push, pop, peek, and isEmpty. (b) What is the running time complexity of your method? Justify. Important Notes: . . You must add the main method in your program to test your implementation. There are no data errors that need to be checked as all the data will be assumed correct.
