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…

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…
