PAT甲级1018. Public Bike Management 题意: 杭州市有公共自行车服务,为世界各地的游客提供了极大的便利.人们可以在任何一个车站租一辆自行车,并将其送回城市的任何其他车站. 公共自行车管理中心(PBMC)不断监测所有车站的实时能力. 如果一个车站正好半满,那么一个车站据说处于完美的状态.如果车站充满或空,PBMC将收集或发送自行车,以调整该车站的状况.此外,所有的车站也将进行调整. 当报告问题站时, PBMC将始终选择到达该站的最短路径.如果有多于一条最短路径,则需要…

Public Bike Management PAT-1018 使用一个vector来存储所有最短路的前驱结点,再通过使用dfs和一个额外的vector记录每一条路径 #include<iostream> #include<cstdio> #include<algorithm> #include<cstring> #include<string> #include<cmath> #include<queue> using…

[思路] 题目生词 figure n. 数字 v. 认为,认定:计算:是……重要部分 The stations are represented by vertices and the roads correspond to the edges. 顶点表示车站,边表示道路. correspond to 相当于 capacity n. 能力:容量 题目大意:给出需要调整的车站编号,从0处出发,一路上顺便调整途径的车站,使得每个车站的车辆数是Cmax的一半,多的带走少的补齐.选最短路,最短相同选从0处…

https://www.patest.cn/contests/pat-a-practise/1018 先用Dijkstra算出最短路,然后二分答案来验证,顺便求出剩余最小,然后再从终点dfs回去求出路径 #include<cstdio> #include<string> #include<cstring> #include<vector> #include<iostream> #include<queue> #include<a…

先找出可能在最短路上的边,图变成了一个DAG,然后在新图上DFS求答案就可以了. #include<iostream> #include<cstring> #include<cmath> #include<algorithm> #include<cstdio> #include<queue> #include<vector> using namespace std; const int INF=0x7FFFFFFF; ;…

思路:你的答案必须满足三个条件: 1.在所有路径中选择最短的: 2.如果路径相等,则选择从PBMC中送出最少的: 3.如果路径相等且PBMC送出的车也相等,则选择带回最少的. 注意:这题很恶心,你要考虑–在最后计算发车数和返回车数时,首先要从sp开始反向寻找第一个缺车的站(由于发车是单向的,路径上靠近PBMC的站可以将多出的车交给较远的缺车的站,但较远的站之后不能将多出的车返还给较近的缺车站,其后多出的车最后全部返还给PBMC了,因此发车数要从第一个缺车的站开始往前计算),之后多出的车全部计入返…

题目:https://pintia.cn/problem-sets/994805342720868352/problems/994805489282433024 题意: 给定一个图,一个目的地和每个节点上的自行车数量. 现在要找到从0到目的地的一条最短路,并且对这条路径上的点的自行车数目进行调度使得每个节点的自行车数量都是某个定值. 可以从前面经过的节点搬运自行车到后面的节点,0号节点的自行车是无穷多的. 如果最短路不唯一,要求找到从0号带出的自行车数量最小的方案. 如果还是不唯一,要求找到带回…

题目及题解 https://blog.csdn.net/CV_Jason/article/details/81385228 迪杰斯特拉重新认识 两个核心的存储结构: int dis[n]: //记录每个点到源头的最短距离 bool mark[n]; //标记每个顶点到 /*如果想要保存路径,创建一个 二维数组,或者vector[n], 里面的每个一维数组表示到达该节点的前一个节点,在(u为当前选出的新节点)当dis[v]==dis[u]+e[u][v],说明通过u到达v的路径也是最短路径,于是把…

#include<bits/stdc++.h>using namespace std;const int inf = 1e9;int sum,n,tar,m;int num[507];int edge[507][507];int u,v,val;int mn=inf,mn_send=inf,mn_back=inf;int cur=0,cur_send=0,cur_back=0;int vis[507];vector<int>cur_path,ans;void dfs(int x){…

这题不能直接在Dijkstra中写这个第一 标尺和第二标尺的要求 因为这是需要完整路径以后才能计算的  所以写完后可以在遍历 #include<bits/stdc++.h> using namespace std; int cmax,n,v,m; const int N=1e3; int weight[N]; int mp[N][N]; const int inf=0x3f3f3f3f; int dis[N]; int vis[N]; vector<int>path[N]; voi…
