Please solve my doubt

Question

Q if any Grammar is LL(1) definitely LALR(1) ?

It is true or false

Please ans explain  in detail.

Answer 1

if any Grammer is LL(1) then it compulsory BUP that means must be CLR(1) , powerful one of BUP definitely satisfy but there is no guarantee of LALR(1).

bcoz BUP is  more powerful than TDP.that means atleast most powerful person must satisfy

Answer 2

False! each LL(1) is CLR(1) but each CLR(1) may or may not be LALR(1). I think there is no relation b/w LL(1) and LALR(1) but LL(1) are proper subet of CLR(1).

Note that, every epsilon free LL(1) grammar is LALR(1).

Comments

LALR is a LR parser uses LALR(1) language, and LL are proper subset of LR languages then, it should be true. ryt.

Among the various LR parsers, only CLR(1) is the strongest of all. So every LL(1) grammar is CLR(1). However, only a proper subset of LALR(1) grammars is LL(1).

Can you explain explain with example which LL(1) but not LALR(1)
