C++队列优化的Bellmanford最短路算法，使用C++实现的Queue improved Bellman-Ford单源最短路算法，在国内还被叫做SPFA。这个程序输入一个图，找到图中的一个点，这个点到最远点的长度最短。图使用邻接表保存。-Optimized Bellmanford C++ queue shortest path algorithm , use C++ achieve Queue improved Bellman-Ford single-source shortest path algorithm, also called domestic SPFA. This program input of a graph, to find a point in the figure, the point to the farthest point of the shortest length. Figure adjacency table holds.
