Riddle 2

You're stuck in a room by yourself with two doors and two computers. One computer must always tell the truth, while the other must always lie. You don't know which is which. One door instantly kills you when you open it, the other you immediently escape. You don't which is which. You can ask one computer one question. How do you escape?

Spoiler:

You ask one computer: What would the other computer tell me?

Because you know that if it's the computer that lies, it will say the opposite of what the other computer would say, which is the bad door. And if it's the honest computer, it would say what the lying computer would say, which is also the bad door. So basically, you ask that question and do the opposite of what you're told to do.

I didn't read the spoiler, by the way. Heard something similar to this before.

Haha. Silly.

I remember reading something like this before. Of course, it was in the context of people rather than technology.

Like the others have said, if you ask the question right, it has no choice but to point you in the right direction anyway. ^_^
