can somebody answer this question?

Give the Context Free Grammars which generate the following languages: a) La = {w ∈ {0, 1} ∗ : w has at least twice as many zeroes as ones }.

Answer 1

Answer #1

The language can begin with either 0 or 1, so we have the following two productions

We can also have the case when the initial two 0's are not consecutive

So the overall grammar will be as follows

This grammar always generates languages with twice as many 0's as 1's
