一个简单实用的自己编写计算器，非常非常非常好用。

构造LR(1)分析程序，利用它进行语法分析，判断给出的符号串是否为该文法识别的句子，了解LR（K）分析方法是严格的从左向右扫描，和自底向上的语法分析方法。-tectonic LR (1) analysis procedure, and use it for syntax analysis, judgment, given the string of symbols to whether the sentence grammar recognition, understanding LR (K) analysis method is strict scan from left to right, and bottom-up syntax analysis.
