树的最小表示法 给定两个有根树的dfs序,问这两棵树是否同构 题解:http://blog.sina.com.cn/s/blog_a4c6b95201017tlz.html 题目要求判断两棵树是否是同构的,思路是用树的最小表示法去做.这里用的最小表示法就是将树的所有子树分别用1个字符串表示,要按字典序排序将他们依依连接起来.连接后如果两个字符串是一模一样的,那么他们必然是同构的.这样原问题就变成了子问题,子树又是一颗新的树. Source Code Problem: User: sdfzyhy…

POJ2502 题目大意:给你一个二维地图,起点终点,以及多条地铁线路(只有相邻两站才可互通)中的站点坐标.步行以及坐地铁的速度: 思路:难点在于建图,一个多小时磨磨蹭蹭,都是因为思路没捋清楚~~,对于每一条地铁线,在输入站点坐标的过程中我们就可以建立图像了:输入完成后,遍历所有的点再建立,以步行为计量单位的图像.就ok啦,然后裸spfa就好了 #include <iostream> #include <vector> #include <string.h> #incl…

[CC-SUBWAY]Subway Ride 题目大意: 一棵\(n(n\le5\times10^5)\)个点的含重边的树,总边数为\(m(m\le10^6)\),每条边有一个颜色.\(q(q\le5\times10^5)\)次询问,每次询问两个结点之间的路径(不经过重复结点)最多包含多少连续的同色段. 思路: 一个显然的结论是,对于连接相同两个点的重边,如果不同的颜色数量\(\le 3\),那么至少有一条边和路径两侧的颜色不相同,这时我们只需要发明一种新的颜色来代替这些颜色即可.因此每条边最多…

◇例题·I◇ Snuke's Subway Trip 题目来源:Atcoder Regular 061 E题(beta版) +传送门+ 一.解析 (1)最短路实现 由于在同一家公司的铁路上移动是不花费的,只有在换乘时会花费1日元.我们可以视换乘的花费为点权——当换乘到不同公司时花费1,同一家公司时花费0. 对于这种点权因情况而变化的题,最常见的做法便是拆点.设节点 u 相连的铁路由 c1,c2,...,cp p个公司修建,则将节点u拆分为节点 uc1~ucp,点uci表示到达点u的铁路是由公司c…
