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)文法的判别需要依次计算FIRST集、FOLLOW集和SELLECT集,然后判断是否为LL(1)文法,最后再进行句子分析。
-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.

实现NFA确定化子集算法程序。DFA是NFA的特例。对每个NFA N一定存在一个DFA M ,使得 L(M)=L(N)。对每个NFA N存在着与之等价的DFA M。从NFA的矩阵表示中可以看出,表项通常是一状态的集合,而在DFA的矩阵表示中,表项是一个状态,NFA到相应的DFA的构造的基本思路是:1.DFA的每一个状态对应NFA的一组状态. 2. DFA使用它的状态去记录在NFA读入一个输入符号后可能达到的所有状态.。-achieve NFA Number algorithm to determine procedures. DFA NFA is a special case. NFA N for each must exist a DFA M, makes L (M) = L (N). N for each NFA exist with the DFA M equivalent. NFA from the matrix can be seen, tables are usually set of a state, and in the matrix DFA said, Form is a state of the corresponding NFA DFA basic structure of ideas : 1.DFA each one corresponds to a group of NFA state. 2. DFA use it to the state records in NFA Reading input into a symbol after all reach the state. .
