Lost in the woods, you finally happen upon a rickety old bridge across a deep ravine. The ravine is too steep to go down and climb back up. You need to know if the bridge is safe. As 'luck' would have it, you recognize that on the other side of the bridge is that dreadful town, "Knight-and-Liarville". Everyone who lives there is a knight (who always tells the truth) or a liar (who always lies). You are tired and you've been lost in Knight-and-Liarville before. You see three men on the other side of the bridge.

You shout out: "Are you a knight?"

The first man says something, but you can't hear what he said.

The second man shouts, "He said he was a knight."

The third man shouts, "No, he didn't. He said he was a liar."

Which man do you ask to find out whether or not the bridge is safe?

let's just ignore the first and focus on the second and third

since they both said to opposite thing then that means that one of them is a liar and the other is a knight

so we ask either of them what will the second(if you asked the third), or what will the third(if you asked the scond) answer if i asked him "is the bridge safe to cross on"

and what ever answer you get then the reel answer is the opposite of what you got
