Description: 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 is used to determine the top-down analysis techniques. LL (1) the meaning is: the first show that L is top-down analysis from left to right scan input strings, the first two L analysis showed that the process is derived using the most left, look to the right one shows that only a symbol will be can decide how derived, that is, to choose which production (rule) for derivation. LL (1) determine the needs of grammar followed by calculation of FIRST sets, FOLLOW sets and SELLECT set, and then determine whether to LL (1) grammar, sentence analysis of the final again.

补充：
程序存在问题：
(1) follow集不能处理：U->xVyVz的情况
(2) 因本人偷懒，本程序为加入文法判断，故
输入的文法必须为LL(1)文法
(3) 您可以帮忙扩充：消除左递归，提取公因子等函数

Description: LL(1)预测分析法（1）判别文法是否为LL(1)文法。为此需要依次计算FIRST集、FOLLOW集和SELLECT集,根据SELLECT集可判断文法否为LL(1)文法。
（2）构造出分析表。根据SELLECT集和文法产生式构造出LL(1)分析表。
（3）进行句子分析。依据分析表判断出某句子是否为给定文法的句子。
