Question

Consider the grammar shown below.
$S\to CC$
$C\to cC|d$

The grammar is

• A. LL (1)
• B. SLR (1) but not LL(1)
• C. LALR (1) but not SLR (1)
• D. LR (1) but not LALR (1)

Answer 1

The correct option is A LL (1)

Consider the grammar

$S\to CC$
$C\to cC|d$
The above grammar is LL(1)
[it is unambiguous, not left recursive and left factored].
It is also LR(0) grammar, hence it is SLR(1), LALR(1) and CLR(1).

Therefore option (a) matches correctly.
