Let L be a strict subset of LACC (i.e. L c LACC). Then L is ( always / sometimes / never ) decidable.
Given: 1. ∀s1,s2 Subset(s1,s2) ⇔ [∀x Member(x,s1) ⇒ Member(x,s2)].Prove: H. ∀s1,s2,s3 [Subset(s1,s2) ∧ Subset(s2,s3)] ⇒ Subset(s1,s3).
Consider the language L = {a'bck | i + j,j # k, i + k}; it is not a context- free language. Show that it nevertheless satisfies the conditions of the context-free pumping lemma, that i s, show that there exists an m so that for all strings w in L of length at least m, we can write w = uvxyz with |vxy| 1, such that Vi > 0 : uv'xy'z € L.
