通过BFS可以求出到每个站点的最小花费. 每次从队首取出一个点,枚举所有它能花费1块钱就到达的线路,通过两遍递推求出最大时间. 注意到每个点和每条线路只有第一次使用时有用,所以总时间复杂度为$O(n+m)$. #include<cstdio> #include<cstring> #include<algorithm> typedef unsigned long long ll; const int N=300010,M=100010,E=1000010,inf=1000…

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…
