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…

题意: 输入N,M,S,D(N,M<=500,0<S,D<N),接下来M行输入一条边的起点,终点,通过时间和通过花费.求花费最小的最短路,输入这条路径包含起点终点,通过时间和通过花费. trick: 找了半小时bug终于发现是给dis数组赋初值时范围是1~N,这道题点是从0~N-1的,故初次只通过了第0组数据,初始化改一下边界即可AC. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h>…
