Sailboat Race Ranking

Programming Challenge 7 in Chapter 3 asked you to create an application that tracks the performance of sailboats in five races. That version of the application only calculated the total points for each boat. In this new version, you are asked to rank the boats, assigning them first, second, and third place. Also, you will need to perform the following input validations:

1. 1. All input values must be valid integers.
2. 2. In any column (a single race), the three integers must add up to 6 (1 + 2 + 3, in any order). We assume there are no tie scores.

When one of these input validations fails, display an appropriate message in the status bar. You do not need to customize the message for each input field, but you must explain the nature of the error (nonnumeric, or duplicate values for a single race). Figure 4-37 shows a sample of the program as the user is entering values, and has incorrectly entered the rankings for Race #1. If all inputs are correct, display the rankings, as shown in the sample in Figure 4-38. It is possible for two or more boats to have the same total race score. In that case, display the word "TIE" on the status bar, and turn the font color for all three scores to the color Red. An example of tie scores is shown in Figure 4-39.

NOTE: There are six ways of arranging the rankings of three sailboats, so your nested IF statement must be able to create these arrangements. The arrangements are: (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1).
