You are standing outside a closed room. Inside the room is a single light bulb.
Outside the room are three switches. Only one of them controls the light bulb. The other two do nothing.
You may flip the switches however you like, but you may enter the room only once. Once you enter, you cannot touch the switches again.
Question: How can you determine which switch controls the light bulb?
