If D = {ww|w elememnt of {0,1}*} and s = 0^p 1^p 0 0^p 1^p = uv^ixy^iz prove D is not a context free language by using the pumping lemma. Apparently the answer has to do with the 3rd condition of the pumping lemma (|vxy| <= p) Please don't just provide the answer. I have the answer. Please explain why with examples.
