Am I missing something? The only rules we have are BAB -> AAA and BBB -> BB, and we start with only A, no B, so neither of those rules can be used, so the answer is no?

EDIT: Ah, looks like you cant put emoji in HN comments. Imagine there's apples in there

The relations are bi-directional. So you can change AAA -> BAB and BB -> BBB as well.

Yeah, that was the secret sauce that left me a bit confused

Oh, I see. That makes sense
