简单的LL（1）的分析，具体可见程序，有过程，一目了然，谢谢指教-simple LL (1) analysis, we can see specific procedure, a process, clear, thank you enlighten

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.
