10、ty sequence2 u :二 t3 whi1e defined u4 insert u to the beginning of s5 u := previousu现在序列s就是从s到t的最短路径的顶点集.di jkstra算法的过程dijkstra算法又称为单源最短路径,所谓单源是在一个有向图中,从一个顶点 出发,求该顶点至所冇可到达顶点的最短路径问题。设g二(v, e)是一...
The first line of the input contains integers N, A and B, separated by a single blank character, 2 <= N <= 100, 1 <= A, B <= N, N is the number of intersections in the network, and intersections are numbered from 1 to N. Each of the following N lines contain a sequence of...
