In the land of Truth-tellers, Liars and Alternators, every citizen either always answers truthfully T,
always answers falsely L, or alternates true and false answers A. You encounter, and find yourself
extremely attracted to, a citizen. Before exploring a possible relationship, however, you wonder
whether you'll be dealing with a T, L or A. You may ask a number of yes/no questions to satisfy
your curiosity.

How many questions will it take?
