该段代码实现了chartparsing算法， 这是机器翻译中极其经典的一个算法-This code implements chartparsing algorithm, which is machine translation algorithm for a very classical

同样也是针对编译原理经典虎书的辅助性代码，主要是编译原理Java实现的PJ，本身的编译器也用java写成，希望能有帮助-The same principle also for the compilation of classic books tiger auxiliary code, the main principle is to compile the Java implementation of PJ, the compiler itself is written using java,

一个经典的Tiny编译器的全部源代码，包括词法分析，语法分析，语义分析及中间代码生成-design an application that can compare similarity of two documents.
