<s>[INST] Here is a puzzle I came up with.

You are in a room with three light switches. Each switch corresponds to one of the three light bulbs in a room. Each light bulb is off at the start. You can turn the lights on and off as many times as you want, but you can only enter the room one time to observe the light bulbs. How can you figure out which switch corresponds to which light bulb?[/INST]
