Are the following languages context-free or non-context-free? • If a language is context-free, give a context-free grammar that generates it. • If a language is not context-free, prove this using the pumping lemma. (a) (2.5 marks) A = { akb²c²k+1²m+2 | k ≥ 1, i≥ 1, m≥ 1} (b) (2.5 marks) B = {a²if²k2md²k|i>k>0, m>0} Are the following languages context-free or non-context-free? • If a language is context-free, give a context-free grammar that generates it. • If a language is not context-free, prove this using the pumping lemma.
