Chapter 3, Problem 10RE

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.
