Give a set of four test cases for the algorithm of Exercise •• R5.11 that covers all branches.

Data from Exercise R5.11

Each square on a chess board can be described by a letter and number, such as g5 in the example at right. The following pseudocode describes an algorithm that determines whether a square with a given letter and number is dark (black) or light (white).

Using the procedure in Programming Tip 5.5 , trace this pseudocode with input g5.

If the letter is an a, c, e, org If the number is odd color="black" Else color="white" If the number is even color="black" color="white" Else Else 8 7 65+ 3 N 4 2 a b c d e f g h g5 a b c d e f g h 007 50 in ++ 32 5 1
