Is it also CSL?
Is the following Language, L = {xxxx | x ∈ {0, 1}*} CSL or not? I saw a explanation say that it’s REC, but it didn’t say anything about it not being CSL and I used to think strings like {xx | x ∈ {0, 1}*} are CSL where the same strings keep repeating [like x here]. So is it CSL and please do also tell is there a rule to figure that out?
