Backgammon

  五子棋是有两个人在一盘棋上进行对抗的竞技运动。在对局开始时，先由用户选择哪方先开局，先开局一方将一枚棋子落在一点上，然后由另一方在对方棋周围的交叉点上落子，如此轮流落子，直到某一方首先在棋盘的直线、横线或斜线上形成连续的五子则该方就算获胜。此时，算法结束。当有任何一方想退出时，都可在算法中实现。(Backgammon is a competitive sport confrontation of two people in a game of chess. At the beginning of the game, the first users to choose which side first start, first start the party will be a pawn falls point, and then by the other party on the other chess around the intersection of Lazi, so turns Lazi, until the party first the chessboard straight, horizontal or diagonal to form a continuous five sons even if the party wins. In this case, the algorithm ends. When either party wishes to withdraw from, can be realized in the algorithm.)
