Use the pumping lemma to prove that the following language is not context-free.
$\qquad L = \{ w w w \mid w \in \{a,b\}^*\}$
I am studying for an exam and really trying to understand this question. For some reason the third w is throwing me off.
I first tried using the string $a^p b^p a^p b^p a^p b^p$ but didn't get very far.
The other string I tried to work through it with was $a^p b^p b^p$
Having a hard time figuring out how exactly to split it up.
Any guidance and explanation would be greatly appreciated.
