So: You find yourself in a room that has only 2 exit point doors, that are closed. You can safely exit through one of the 2 doors. If you choose the wrong door, the entire room will explode and kill you instantly.
In the center of the room, is a computer on a table. It is programmed to either ONLY lie or ONLY tell the truth as an ANSWER to ONE QUESTION only, that you can ask it.. You don't know which one it is programmed to do, but you know this variable exists.
What's the question you will ask it to make it choose without doubt, to point you to the correct door?
