<s>[INST] Here's a classic logic problem. There are three switches, but they are not labelled. Each switch corresponds to one of three light bulbs in a room. Each light bulb is either on or off. You can turn the switches on and off as many times as you want, but you can only enter the room to observe the light bulbs one time. How can you figure out which switch corresponds to which light bulb?[/INST]
