Analysis: Find Jimmy from the office through the Forest back home (that is, from point 1 to 2) The shortest path there are how many, in which to meet if you want to go to a to B this road, then there is a to the end of the distance from a to the end of the distance is greater than B.Solution: SPFA algorithm + memory Deep Search1. SPFA find the shortest path from the end point 2 to all other points2, the memory of Dfs from 1 start to other points deep search, the final result is dp[1].#include HD

Question http://acm.hdu.edu.cn/showproblem.php? PID = 1, 1142
I started with this question, but I didn't think it was just a short circuit. I didn't expect a deep search.
First, let's introduce the meaning of this question. I understand that the starting point is "1" and the ending point is "2" on the road between "A and" 2, you can calculate several roads between B and 2 (the distance is smaller than the road between A and 2). A and B are linked ..

Question: There are several shortest paths. First, use the Dijkstra algorithm to find the shortest path between each ver
guess that the three-part method is to make three equal points for the required approximation:we find that LM is lower than RM, so the smallest point we're looking for must be between [LEFT,RM]. Assuming that the lowest point is between [Rm,right], it will appear that the RM has lower points around it now, which is obviously impossible. Similarly. When RM is lower than LM, the lowest point must be within the [Lm,right] range. using this property, we are able to approximate the target point at t
