4. (Non-CFLs) Prove that the following languages are not context-free.
(b) The following language over the alphabet {a, b, c}:
B = {aix | i 0, x {b, c}* , and if i = 1 then x = ww for some string w}.
(Careful: B satisfies the pumping lemma for CFLs! Make sure you understand why, but you dont need to write it down.)
