This article describes how to create an undirected graph's Adjacent matrix and path. The extra cost required for each vertex is the first and the end. No extra cost. Calculate the shortest path between two points in the graph and print the minimum path of the Lexicographic Order. It is required that the Floyd print path be used between multiple groups of points, which is also convenient for NEX [I] [J] to indicate the first path from the I point to th
