Main idea: Enter the first line to give 4 positive integers n, M, S, D, where N (2 The first line outputs the number of different shortest paths and the maximum number of rescue teams that can be convened. The second line outputs the city number that passes through the path from S to D. The numbers are separated by a space, and the output cannot have extra spaces. Idea: How to judge the most short-circuit problem, just start to think is in the if (d

title: Emergency Rescue Ideas: Look at the question: (1) Seeking the shortest path; (2) The number of different shortest paths is recorded, that is, the shortest path may have more than one value, but the path is different; (3) The most popular path is screened on the basis of shortest path; (4) record the path. Solving: Using the most basic Dijkstra directly to find the problem (1); and the question (2) and (3) in fact the same as the solution (1), j
