时间限制 400 ms 内存限制 65536 kB 代码长度限制 16000 B 判题程序 Standard 作者 CHEN, Yue A traveler's map gives the distances between cities along the highways, together with the cost of each highway. Now you are supposed to write a program to help a traveler to decide t…

先处理出最短路上的边.变成一个DAG,然后在DAG上进行DFS. #include<iostream> #include<cstring> #include<cmath> #include<algorithm> #include<cstdio> #include<queue> #include<vector> using namespace std; const int INF=0x7FFFFFFF; ; int n,m,…

和1018思路如出一辙,先求最短路径,再dfs遍历 #include <iostream> #include <cstdio> #include <vector> #include<algorithm> using namespace std; ][], c[][];// distence cost vector<];//到达当前节点的前一个节点 vector<vector<int> > st; //最短距离的路径 vector…

模板题最短路+输出路径如果最短路不唯一,输出cost最小的 #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <cmath> #include <queue> #define INF 0x3f3f3f3f using namespace std; ; int n,m,s,t; struct Edge{ int…
