turn on one light switch and wait for a few mintues. Then turn that one off and turn a different one on. When you enter the room one bulb will be off (switch you never used), one on (second switch you flicked), and one bulb will be off but hot to the touch (bulb you left on for a few mintues).

actual your question may be that we've discover that with the help of getting into the room for decrease than one time. answer is __ merely activate a bulb for couple of minutes and turn it OFF and (the following we call it as swap no: a million) then activate yet another swap (say no:2) (and say the swap which under no circumstances switched ON is not any:3) Then were given to the room and the bulb that is sparkling is for swap 2, and from the bulbs that are literally not sparkling, the bulb that is warm is for swap no:a million, and the bulb that is chilly is for swap no:3

You just flip every single switch at the same time
