Rotation Code

Update the output cells so that the correct rotation code (A, B, or C) is shown for each day number. The rotation pattern is exactly 3 days long and repeats forever: Day 1 = A, Day 2 = B, Day 3 = C, Day 4 = A, Day 5 = B, Day 6 = C, and so on. See Examples

Your solution should use cell references so it updates automatically if the input cells change values.
