这道题网上非常多人都会说easy,水题之类的话,只是我看了下说这种话的人的程序,能够说他们的程序都不及格! 为什么呢?由于他们的程序都是使用简单的二次排序水过(大概你能搜索到的多是这种程序).那样自然能够说不及格了. 由于本题真正的目的是求前k个最大数的问题.这就须要活用高速排序. 求前k个最大数的思路: 1 选取一个数位轴,然后把大于这个数的数放到数列前面.小于这个数的数放到数列后面 2 假设前面的数的数量大于k.那么能够去掉后面的数,递归在前面的数查找前k个最大数 3 假设前面的数的数量小于…

题意:有N个人参加选举,有M个条件,每个条件给出:i和j竞选与否会只要满足二者中的一项即可.问有没有方案使M个条件都满足. 分析:读懂题目即可发现是2-SAT的问题.因为只要每个条件中满足2个中的一个即可,因此将人i拆成 点i表示不竞选,和点i+N表示竞选,根据合取式的满足条件建图跑Tarjan. 最后检查每个i与i+N是否在同一强连通分量中. #include<stdio.h> #include<iostream> #include<algorithm> #inclu…

选主 使用ZooKeeper选主的一个简单方法是,在创建znode时使用Sequence和Ephemeral标志.主要思想是,使用一个znode,比如"/election",每个客户端创建一个子节点"/election/guid-n_",并同时使用Sequence和Ephemeral标志.使用sequence标志后ZooKeeper会自动递增序列号.拥有最小编号的节点就是主节点. 这还不是全部,同时还需要watch主节点的失效,在当前主节点失效后,会产生新的主节点.…
