UnLinker编译原理实验
- 编译原理实验 为UnLinker.java文件中的UnLinker类实现成员函数String clean(String text). 函数clean的功能是屏蔽字符串参数text中的网页链接信息，并返回屏蔽后的结果；如果无需屏蔽，则返回原来的字符串. 每个网页链接从左至右依次分成前缀，域名和后缀三部分-Compilation Principle experiment UnLinker.java file UnLinker class implements member functions Str
word
- 使用C语言开发的一个简单的词法分析器。矩阵。最后生成token串。-Developed using C language with a simple lexical analyzer. Matrix. Last generated token string.
lll
- 实现了LL(1)文法分析，包括构造First、Follow集、预测分析表，并可检查输入串是否被接受。-The implementation of LL(1) analysis, including constructing the First, Follow set, Predictive Parsing Table. It can also test a string whether it is accepeted.
根据某一LL(1)文法编制调试预测分析程序
- 根据某一LL(1)文法编制调试预测分析程序，以便对任意输入的符号串进行分析。 本次实验的LL(1)文法为表达式文法： E→E+T | T T→T*F | F F→i | (E) 编写识别表达式文法的合法句子的预测分析程序，对输入的任意符号串，给出分析过程及分析结果。分析过程要求输出步骤、分析栈、剩余输入串和所用产生式。如果该符号串不是表达式文法的合法句子，要给出尽量详细的错误提示。-According to an LL (1) grammar analysis of

- 一个简单的词法分析器，能够识别基本的单词符号串-A simple lexical analyzer can identify the basic symbol string of words
LR1
- 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。-Construct LR (1) analytical procedures, and use it to parse sentences of whether the judgment given string of symbols for grammar recognition LR (K) analysis method is stri
FAScanner
- 单词是高级语言中有实在意义的最小语法单位，而单词又由字符组成。每一种高级语言都定义一组字符集。单词可大致分为五类：基本字，标识符，整常数，运算符，界限符。从输入的源程序字符串中逐个地把这些单词识别出来，并转化成机器比较容易使用的内码形式，这是词法分析器的主要任务。-The word is the smallest grammatical unit actual significance of the high-level language, the word characters. Each d
LL1Parsing
- 语法分析阶段的主要任务是组词成句。每一种语言都有一组文法。按照这些文法，可以由单词组成语法单位，如短语、语句、过程和程序。语法分析就是通过语法分解，确定整个输入串能否构成语法上正确的句子和程序等。-The main task of the parsing stage is a group of words into a sentence. Each language has a set of grammar. These grammars can be composed by the word

non-recursive
- 建立文法及其LL(1)分析表表示的数据结构，设计并实现相应的预测分析器，对源程序经词法分析后生成的二元式代码流进行预测分析，如果输入串是文法定义的句子则输出“是”，否则输出“否”。-提示：" s"以后的内容没有被翻译，单次翻译最多1000字 努力翻译中，请稍后… A grammar and LL (1) of the table that the data structure, design and implement the corresponding prediction
