You are in a room with three light switches. In another room is a lightbulb. Each switch can be flipped "ON" or "OFF," but only one switch gives power to the lightbulb. The goal is to figure out which switch is connected to the lightbulb.You are only allowed to enter the room with the lightbulb once, and you cannot see the light from where you are.
