Dijkstra算法--c++源代码

单源最短路径问题，或者称为最短路径问题，是要确定从s到V中没一个其他

顶点的距离，这里从顶点s到x的距离定义为从s到x的最短路径问题。-Dijkstra algorithm- c++ source code for single-source shortest path problem, or known as the shortest path problem is to determine V from s to no one other vertex in the distance here from the vertex s to x is defined as the distance from s to x of the the shortest path problem.
