1. Tic-Tac-Twice is a game invented by Pat Baggett and Andrzej Ehrenfeucht. It is distributed by the Aristoplay company. The rules are simple, starting with two 4x4 boards that rules each have a pattern of 16 letters (or other objects). If you use the letters A through P, then the two boards have these patterns:

The two players (human and computer) take alternate turns. During your turn, you can place a checker of your color on an empty spot on Board 1. At the same time, you put a checker of your color on the square in Block 2 with the same letter. For example, if you put your checker in the bottom-left corner of Board 1 (letter M), then you would simultaneously put one of your checkers on the third spot of the top row of Board 2 (also letter M).

You win the game by having four of your circles in a row (horizontally, diagonally, or vertically) on either of the boards. Note that you don’t need four in a row on both boards, just on one of them. Implement a class that lets a user play TicTac-Twice against the computer. Use the AbstractGame class from Section 13.4 as your superclass.
