Slide Sorter Program

[mattwilliams]

Hey everybody! I really need some help with a code I have no idea on how to even start. It is supposed to be able to accept the plays choice for a move, check to see if the move is legal, and then it is supposed to swap the appropriate pieces. At the end of the program it is supposed to congratulate the player and ask if they want to play again or not. I would really appreciate help on this program!
