设置一个静态堆栈，编写它的基本操作后，在图类型设计时，构造一个最短路径矩阵和一个最短路径长度矩阵，使用FLOYD算法得出最短路径后，利用堆栈的性质输出最短路径和最短路径长度-Set up a static stack, the preparation of its basic operation, the type of design in the plan, construct a shortest path matrix and a shortest path length matrix, use FLOYD shortest path algorithm derived using the stack nature of the output the shortest path and the shortest path length
