Now give you the roadmap to find a route that takes the least amount of time from the starting point near her home (there can be multiple) to the terminal near the friend's home (only one). Each site is numbered from 1 to N. idea: At first I was directly without the brain using the DIJ algorithm to do the results in the slightest surprise (TLE), fuck.

Always have n stations, M route, known he can from the W stations to travel, to arrive at the destination s the minimum time spent. If not, then output-1.Parse: Dijkstra algorithm, but the direct use of W-Dijkstra, will time out. Here are two ideas:1. Set the person's location to site 0, then connect the site 0 and the W starting point, which is equivalent

The inverse of the bellman-ford is not optimized, for each side of the n-1 times to relax, so as to try to update the shortest distance of the end of each edge, and SPFA directly from the beginning of the starting point to find the adjacent side, determine whether it can be updated, and determine whether to
