这题做的心很累,我用的还是 1018的思路做的,但是 使用dfs 求最大人数对于某些有问题(现在也不知道错哪了), 看了别人的代码后才发现,其实完全不用这么麻烦,只需设置一个点的权重,一遍DJ(自创简称)下来,直接出答案 收获: 1.DJ不需要存储具体路径也能知道最短路径有几条: 在DJ外设置一个road[n]数组,初始为0:road[源]=1://road表示,从源出发,到n的最短路径条数 在更新环节 for() { if当dis[u] + e[u][v] < dis[v] road[v]=r…

给出N个城市,m条无向边.每个城市中都有一定数目的救援小组,所有边的边权已知.现在给出起点和终点,求从起点到终点的最短路径条数及最短经上的救缓小组数目只和.如果有多条最短路径,则输出数目只和最大的 Dijkstra 做法 #include<bits/stdc++.h> using namespace std; int n,m,s,u; ; const int inf=0x3f3f3f3f; int mp[N][N]; int dis[N]; bool vis[N]; int value[N];…

解题步骤: 1.初始化:设置mat[][]存放点之间的距离,vis[]存放点的选取情况,people[]存放初始时每个城市的人数,man[]存放到达每个城市的救援队的最多的人数,num[]存放到达每个城市的最多的人数(在最短路径的基础之上),dist[]存放从起点开始到达每个城市的最短的路径(随着每次选取点而更新) 2.核心算法:按照Dijkstra算法思想,从起点出发,不断选择一个点使得通过该点到达其他点的距离比直接通过已知点到达的距离更短,则更新最短距离数组dist[],这里分为两种情况1:…
