纯用 字符 和数组编的五子棋，棋盘也是用字符画的。

编了1上午了，主要是算法跟按键比较烦，发现有bug-- 按键速度过快会产生延时显示，可能是算法不好。

操作：玩家1： a,s,w,d（方向） 空格（落子）

玩家2： 上、下、左、右 回车 （落子）

ESC： 退出

Made up a morning, mainly the algorithm with key trouble, trouble, found bug- buttons too quickly will produce delay indicates that the algorithm is not good. Action: Player 1: a, s, w, d (direction) space (expanded store-opening) player 2: up, down, left and right carriage return (expanded store-opening) ESC: Quit
