可以用floyd 直接记录相应路径 太棒了! http://blog.csdn.net/ice_crazy/article/details/7785111 #include"stdio.h" #include"string.h" int n; int tax[111]; int map[111][111]; int path[111][111]; void floyd() { int temp; int k,i,l; for(i=1;i<=n;i++) for…

链接:传送门 题意:有 n 个城市,从城市 i 到城市 j 需要话费 Aij ,当穿越城市 i 的时候还需要话费额外的 Bi ( 起点终点两个城市不算穿越 ),给出 n × n 大小的城市关系图,-1 代表两个城市无法连通,询问若干次,求出每次询问的两个城市间的最少花费以及打印出路线图 思路:经典最短路打印路径问题,直接使用一个二维数组 path[i][j] 记录由点 i 到点 j 最短路的最后后继点,这道题关键是当松弛操作相等时,i 到 j 的最短距离是可以由 k 进行跳转的,这时候需要判断这…

<题目链接> 题目大意:给你一张图,有n个点,每个点都有需要缴的税,两个直接相连点之间的道路也有需要花费的费用.现在进行多次询问,给定起点和终点,输出给定起点和终点之间最少花费是多少,并且输出最少花费所走的路径,如果有多条路径花费最少,则输出字典序最小的那条. 解题分析: 输出最短路的路径问题,需要注意的是,题目要求输出的最短路径的字典序最小,所以我们在每次松弛的时候,都需要加上判断.如果有多个点的最短路相同,则用DFS求出它们之前走过的路径,并且进行比较,然后选字典序最小的那条. #incl…
