种类并查集·POJ-1703 题目大意: 和食物链一样,该题询问的是是否在一个帮派中, A a b : 询问ab是否在一个帮派中; B a b : 告知你a b不是一个帮派的; AC代码:...猜你喜欢POJ 1703 (多集合 并查集) ...种类并查集(POJ1703) 图学的有点自闭,再加上用到了并查集、模拟栈、搜索,先补一下这些...
题意:给你t组数据,每组数据给你编号为1-n的坏人,这些坏人要么属于团伙A,要么属于团伙B,然后给你m次操作: A操作:询问x和y是不是同一个团伙 D操作:告诉你x和y不是同一个团伙 思路:和POJ 1182 食物链是一样的。http://www.cnblogs.com/sevenun/p/5474343.html AC代码: ...POJ-1703 Find them, Catch...
