---++ Hints
   1. [[CSS121S2023Lab4H1][Program design]]
   1. [[CSC121S2023Lab4H2][I feel overwhelmed.  How should I start?]]
   1. [[CSC121S2023Lab4H2a][That was ok, but I am still overwhelmed.  What else do you have?]]
   1. [[CSC121S2023Lab4H3][Hint for file problems]]
   1. [[CSC121S2023Lab4H4][Once the user gets 4 colors right, it seems like row is always guessed correctly no matter what]]
   1. [[CSC121S2023Lab4H5][I get too many lines of output]]
---++ Optional improvements
Optional improvements should ONLY be worked on once the program is completing working.  In addition, the work is to be done on your own with little if any help for lab assistants or the instructor.
   1 Allow the user to input the colors as a string and the code not be case sensitive.
   1 Handle the exception of a bad file.
   1 Output the number of rows correctly
