题意与分析 2018ICPC北京站A题. 题意是这样的,给定若干人的武力值大小(A B的意思是A比B厉害),问到第几行会出现矛盾. 这题不能出现思维定势,看到矛盾就是矛盾并查集--A>B.A>C是不能推出B>C或者B<C的.相反,大于小于是一种偏序关系,是可以建立有向图的.那么,如果这个有向图中出现了环,就是矛盾的. 问题于是转化为有向图判环问题,这里简单说一下有向图和无向图的判环方法. a) 无向图 删除所有度<=1的顶点及相关的边,并将另外与这些边相关的其它顶点的度减一.…

searcher.Search(types.SearchRequest{Text: "百度中国"}) // 查找满足搜索条件的文档,此函数线程安全 func (engine *Engine) Search(request types.SearchRequest) (output types.SearchResponse) { if !engine.initialized { log.Fatal("必须先初始化引擎") } var rankOptions types.…
