[CC-ADJLEAF2]Adjacent Leaves 题目大意: 给定一棵有根树,考虑从根开始进行DFS,将所有叶子按照被遍历到的顺序排列得到一个序列. 定义一个叶子集合合法,当且仅当存在一种DFS的方式使得这个叶子集合在序列中的出现位置是一个连续子串. 给出一个\(n(n\le5\times10^5)\)个点的无根树,\(m(m\le5\times10^5)\)次询问,求以\(R\)为根的情况下叶子集合\(S(\sum|S|\le5\times10^5)\)是否合法. 思路: 定义\(le…

Description As we all know caterpillars love to eat leaves. Usually, a caterpillar sits on leaf, eats as much of it as it can (or wants), then stretches out to its full length to reach a new leaf with its front end, and finally "hops" to it by c…

 http://blog.csdn.net/geniusluzh/article/details/6619575 在说Tarjan算法解决桥和边双连通分量问题之前我们先来回顾一下Tarjan算法是如何求解强连通分量的. Tarjan算法在求解强连通分量的时候,通过引入dfs过程中对一个点访问的顺序dfsNum(也就是在访问该点之前已经访问的点的个数)和一个点可以到达的最小的dfsNum的low数组,当我们遇到一个顶点的dfsNum值等于low值,那么该点就是一个强连通分量的根.因为我们在dfs的…

二叉树及其遍历 一遍AC,挺开心的hhh~ 简单讲下思路:叶子,顾名思义就是没有左右子树的结点.由于题目要求,叶子结点的输出顺序是从上往下,从左往右.所以用层序遍历法. 当然,这里先找到root树的根.运用队列,将root进队列.然后依次将队头出队,若是叶子则输出,否则且将其有的左右孩子进队,达到层序遍历,就是从上往下,从左往右的要求. 当队列为空,即遍历整个树后,结束. Given a tree, you are supposed to list all the leaves in the o…
