前言: 本题是我在浏览了柳神的代码后,记下的一次半转载式笔记,不经感叹柳神的强大orz,这里给出柳神的题解地址:https://blog.csdn.net/liuchuo/article/details/52316405 题意: 有一个租借自行车的系统由n个点组成,用户可以在这n个点任意一个点借车或者还车,每个点都遵循一个共同的上限c,这里我们称一个点的状态时完美的如果这个点的车的数量为c/2,(每个点由1~n标号),而我们的出发点为0点,整个系统每次会有一个sp点发出警报,说明这个sp点的自行…

题意: 输入四个正整数C,N,S,M(c<=100,n<=500),分别表示每个自行车站的最大容量,车站个数,此次行动的终点站以及接下来的M行输入即通路.接下来输入一行N个正整数表示每个自行车站初始拥有的自行车数量,接下来输入M行每行包含三个正整数分别表示一条双向边的端点以及这条路的长度.求去往终点车站一次所经历的最短路,多条最短路则优先少带出车辆,次优先少带回车辆.(路上经过站点时需要把该站点的车辆变为最大容量的一半) AAAAAccepted code: #include<bits/…
