Professor Merlin has asked you to help him. He has 30 total students in his class, but he is not sure that all of them took his last exam. He wants to average the grades for his last exam in his medieval literature course and then determine how many students scored above the average and how many scored below. Without arrays you would have to enter all the test scores, find their average, and then enter them again to determine how many exceed the average. But you know how to use arrays, so you won't need to enter the input a second time. Since all students might not have taken the test, less than 30 scores may be entered.
