There are 3 SPST wall switches on the wall outside the room, and each switch controls a single lamp inside the room. They are 1,2,3.
You can not see the effect of turning on any switch when you are outside the room.
You can manipulate the switches in any way.
After you are done with the switches, you may enter the room once and close the door behind you.
