Problem Statement

You are standing in a hallway outside a closed room. On the wall next to the door are three light switches, labeled 1, 2, and 3. Inside the room, there is a single incandescent light bulb. You cannot see into the room from the hallway. You are allowed to flip the switches in any combination and leave them in any position you want. However, you can only enter the room once to inspect the light bulb. How can you determine with absolute certainty which switch controls the light bulb?
