博主欢迎转载,但请给出本文链接,我尊重你,你尊重我,谢谢~http://www.cnblogs.com/chenxiwenruo/p/6789799.html特别不喜欢那些随便转载别人的原创文章又不给出链接的所以不准偷偷复制博主的博客噢~~ 先来扩展一下知识哈密顿图:哈密顿图是一个无向图,由指定的起点通往指定的重点,途中经过所有节点有且只经过一次.在图论中,通常指的是哈密顿回路,即经过图中所有顶点有且只有一次,最终回到出发点.哈密顿回路为NP完全问题,暂不存在多项式内的解法. 欧拉图:类似的有欧…
题意:包含图中所有结点的简单环称为汉密尔顿环.给出无向图,然后给出k个查询,问每个查询是否是汉密尔顿环. 思路:根据题目可知,我们需要判断一下几个条件:(1).首先保证给定的环相邻两结点是连通的:(2).若图结点个数为n,则环的结点个数必须是n+1:(3).环的起点和终点必须相同:(4).除了首尾结点外,其余结点有且仅有出现过一次. 注意点:因为会多次查询,因此记得在每次查询前进行初始化!(这个点经常出错!画时间找这种错误非常浪费!) 代码: #include <cstdio> #includ…
