根據(jù)判斷一個(gè)文法是LL(1)文法的三個(gè)條件，逐一實(shí)現(xiàn)其判別條件的算法實(shí)現(xiàn)。
滿足是LL(1)文法的三個(gè)條件：
(1)文法不含有左遞歸
(2)對(duì)于文法中每一個(gè)非終結(jié)符A，若它存在某個(gè)候選首符
集兩兩不相交，即，若A→α1|α2|…|αn，則first(αi)∩first(αj)=Φ (i≠j)
(3)對(duì)文法中的每個(gè)非終結(jié)符A，若它存在某個(gè)候選首符集包含ε，則first(A)∩follow(A)=Φ。
使用高級(jí)語言編寫和調(diào)試一個(gè)判斷文法是不是LL(1)文法的程序。程序通過給出的文法，首先判斷文法是否含有左遞歸，若沒有含有則求出其FIRST()集和FOLLOW()集。根據(jù)FIRST()集和FO
