0. You cannot divide by 0, that is why it is on top.
If I enter a door that leads to doom, which door will be to my left: the right one or the left one? (The Truthful one will remain silent if the outermost one leads to death, and the Liar will say it's the right one. If the right door leads to death, then the Truthful one will say that the left one is on the left, and the Liar—the right one.) I WAS SOLVING FOR THE CASE WHERE THEY BOTH ANSWER.
I didn't understand anything :D I always thought that the left one is the left door, and it simply cannot be the right one :) And which of the doors is the outermost?
And only one gatekeeper answers a single question
