一个简单的编译器的实现程序,他展示了大量的数据类型和抽象数据类型,以及对字符串进行解析的技术-a simple compiler in procedures, he showed a lot of data types and abstract data types, and the right strings in the technical analysis

用弗洛伊德算法实现最短路径的求解，用到的抽象数据类型为邻接矩阵类型和有向图类型类型-Floyd algorithm to achieve the shortest path to solve abstract data types used in the adjacency matrix type and have the type of diagram types
