Hi
I'm battling with the second question in the second assignment, where they want one to create a CFG for some language.
What I don't understand at this point is the hint provided in the textbook.

Hint: think of words as (ab)(ba)(ab) NOTE I removed the power signs ppqqrr
how can ba be generated from abab??? again NOTE I removed the power signs xyzw
