这种题自己写吧,题里状态定义个变量,然后判断邻点这些都是方法,然后题里面if要怎么用都给你说清楚了 题了有如果的地方就是一个if语句然后跟着题里的如果把条件写完了 结果也出来了
围棋有几种变化是一个老问题了,比较粗浅的说法是3的19乘19次方,意思就是棋盘上每个点有空、黑、白三种状态,总共有19*19个点,所以得出这个结果。但实际上并没有那么多,因为在那么多状态中,有很大一部分是不可能出现的状态,也就是盘面上有死棋的状态。比如整个棋盘上布满棋子的状态都是不可能的,而这种状态就有2的19*19次方之多。?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /

按围棋规则编写算法计算每颗棋子的气,可以根据棋盘经纬度及周边棋子的个数来判断;
按围棋规则连成片的棋子共享所有的气,将连成片的棋子定义为一个棋子组的对象,以该片棋子经纬度最小的那个棋子做为该对象的唯一标记,在每颗棋子落子的时候,就会发生棋子组属性变化,包括棋子组的合并,棋子组气数的变化等各类情况;
为了方便发现每次落子会影响到的棋子组,可以将每个棋子组的气点经纬度做为索引,该索引也需要随着棋子组的变化而变化;
按围棋规则气数等于0的棋子组为死棋,当每颗棋子落子后,更新所有棋子组的信息后,遍历将所有气数为0的棋子组从棋盘移除。考虑到“打劫”规则,一方落子后,先判断对方死棋,再判断己方死棋,符合“打劫”情况还需要额外记录次数,防止棋盘陷入僵局;
