题意:看样子很多人都把这题目看错了,以为是求最短路的条数.真正的意思是:假设 A和B 是相连的,当前在 A 处, 如果 A 到终点的最短距离大于 B 到终点的最短距离,则可以从 A 通往 B 处,问满足这种的条件的从办公室到家的路径条数. 分析:1.以终点 2 为起点 Dijkstra跑一边最短路,找到所有点到2的最短距离: 2.直接DFS记忆化搜索. 注意:记忆化搜索时的return值,否则此很容易TLE 解法1:O(n^2) #include<iostream> #inclu…

之前很认真地看了用优先队列来实现Dijkstra这块,借鉴了小白书上的代码模板后,便拿这道题来试试水了.这道题的大意就是问你从地点1到地点2有多少条满足条件的路径(假设该路径经过 1->...-> b -> a ->...-> 2,那么d[b]必须小于d[a],其中d[b],d[a]分别是指 b,a 到地点2的最短距离),所以大体做法就是先求出以2为起点的单源最短路径,然后利用深搜dfs(v)表示 v顶点到2的满足以上条件的路径数,最后答案便是dfs(1),当然要加个记忆化.…
