If you read until this far and is still having trouble, some tips for you:

1) It is not a single tree, but a forest.

2) Not every line has a pair of names.

3) Do consider some cases: a.a a.a, a.a no.parent, and no.child a.a

I just got AC, but this problem gave me some minor headaches.

Good luck!
