Student Letter Grade Class

Create a class named Student that stores three integer test scores (math, science, and english) in three fields. Give it a constructor that takes math, science, and english (in that order). Add a method Average() that returns the integer average of the three scores using integer division ((math + science + english) / 3). Add a method Grade() that returns a letter: "A" if the average is 90 or more, "B" if 80 or more, "C" if 70 or more, otherwise "F". The runner code will create a Student and print Grade(). All test cases use scores whose sum divides evenly by 3.
