What can be said about the given language? $L = \left \{ ab^{n}a^{n}|n&gt;0 \right \} \bigcup  \left \{ aab^ka^{2k} | k&gt;0 \right \}$



What can be said about the given language L ?



According to me, I think it is CFL and not DCFL as I tried to somehow parse it through a NPDA but not sure though.
The words in the first part start with $ab$, those in the second part start with $aa$.

That should help.
