  /*
   Exercise 9:
   Set the correct background color depending on the style that is passed in:
   1. initial should set the background color to black and the border color to gray
   2. incorrect should set the background and border color to a red-green-blue-alpha (RGBA) value of 0.23, 0.23, 0.24, 1.0 respectively
   3. correctLetterOnly should set the background and border color to a RGBA value of 0.69, 0.63, 0.30, 1.0 respectively
   4. correctLetterAndPosition should set the background and border color to a RGBA value of 0.38, 0.55, 0.33, 1.0 respectively

   Tip 1: Use a switch-case statement to enumerate among the possible values of LetterCellStyle
   Tip 2: `contentView` is a UIView. Look at the documentation to see what property you can change to modify its background color
   Tip 3: Look at what initializers UIColor has in the API documentation
   Tip 4: Look above at the init method to see how to change the borderColor
   
   // Checkpoint: After finishing this exercise, you should now see that the board is accurately colored based on your guess! If it's not working, make sure you have done this exercise correctly.
