Given a graph, n vertices, m edges, and N values are extremely small. For each edge, there are parameters such as AI, Bi, CI, PI, and RI, it indicates that the edge is from AI to Bi. If the edge passes through CI, the cost is pi. Otherwise, the cost is Ri, and the minimum cost from 1 to n is calculated. F [I, j] is used as the node, and I indicates the current vertex. After J is converted to the binary number, the value 0 indicates that this is not performed, 1 indicates that the spfa is success
