Question 2. Let L be the language given below.

L = {a n b 2n : n ≥ 0} = {λ, abb, aabbbb, aaabbbbbb, . . .}

Find production rules for a grammar that generates L.

Answer 1

Answer #1

Following are the productions for the grammar

$S\rightarrow \lambda \, | \, ASB$

$A\rightarrow a$

$B \rightarrow bb$

As we can see, these rules are enough to generate the given language
