5. Tic-Tac-Toe, Part 5 (20 Points) Save a copy of your program, and add a menu to the single player mode that allows the user to select a difficulty: easy, medium, or hard. The easy mode should be the same as your previous single player mode; the computer selects a move at random. For the medium difficulty, the computer should try to use the center square first, then the corner squares, and lastly the non-corners. For hard difficulty, the computer should first check to see if there are any rows, columns, or diagonals with two of the same letter and move to fill the empty spot if there are. Ifthere aren't, it should follow the same logic as the medium difficulty. Modify your makeComputerMove() function to take an integer indicating the difficulty as an argument. See the .out file download for a complete working example. 5.
