编译原理LL1分析表- Translation principle LL1 analytical table

一个带界面的词法分析器～～界面比较简练友好，适合初学者使用-An interface with a lexical analyzer ~ ~ more concise and friendly interface, suitable for beginners to use ~~~~~

设计、编制、调试一个典型的语法分析程序，实现对如下文法的递归子程序法分析，进一 步掌握常用的语法分析方法。-Design, preparation, testing a typical parser to realize the following grammar for a recursive subroutine Analysis, to further understand the syntax of commonly used analytical methods.

这是一个利用水平集方法进行分割的方法，是目前使用越来越多的方法，并且有严格的数学依据-This is a level set method using segmentation method is currently used by more and more ways, and has a strict mathematical basis for

1.The content is too simple 2.Is not a sourcecode or document 3.lost some files 4.Description is not detailed or not correct 5.Compressed file has password 6.Sourcecode duplicate or already exist po

LL(1)文法使用的是确定的自顶向下的分析技术。LL(1)的含义是：第一个L表明自顶向下分析是从左向右扫描输入串，第2个L表明分析过程中将使用最左推导，1表明只需向右看一个符号便可决定如何推导，即选择哪个产生式(规则)进行推导。-LL (1) grammar using a set top-down analysis techniques. LL (1) the meaning is: the first one L shows a top-down analysis is a scan input string from left to right, the first two L shows the analysis process will be the most left-derivation, one that will be just right to see a sign can decide how to derive, choose what Production (rules) for derivation. LL (1) grammar, followed by calculation of the discriminant needs FIRST sets, FOLLOW sets and SELLECT set, and then determine whether to LL (1) grammar, the last sentence further analysis.
