        From ""."cd", if Alice appends b to "b":"cd", then there are no moves, so she wins.

          I guess I'm not understanding the problem correctly then... why are there no moves after "b,cd"? Can't Bob follow with "ab","cd" ?

            Oh I think I already understood. So when they refer to appending characters, it means that if A' already has something, you can only append characters at the end, right? So that's why if Alice appends appends "b" to A' so the position becomes "b","cd", then no additional letters can be appended and Bob can't do any move, right?

                Can A'=ba and B'=ecd be an example? Or A' and B' will always be lexicographically balanced?
