R3.10 Each square on a chess board can be described by a letter and number, such as g5 in this example:

The following pseudocode describes an algorithm that determines whether a square with a given letter and number is dark (black) or light (white).

If the letter is an a, c, e, or g If the number is odd color = "black" Else color = "white", Else If the number is even color = "black" Else color = "white"

Using the procedure in Programming Tip 3.5, trace this pseudocode with input g5.

R3.11 Give a set of four test cases for the algorithm of Exercise R3.10 that covers all branches. (included R3.10)
