There are two rooms separating by a wall, one room has three lamps, the one one has three switches, can you tell how to find out which switch is for which lamp if you only allow to look at other room once. (Question from Bill Gates, he said if anyone can answer this question in five minutes, he would hire that person.) So far I asked many people this question, only one guy could answer this question within 5 minutes, he was a geek though.
Well, first time that I have heard this one (honest). Here is what I would do: turn the first switch on, turn the second switch off, and disassemble the third switch and wire a disconnect timer into it, set it for one minute, and turn the switch on.
Then go to the Lamp Room and wait 1 minute. The lamp that was on the whole time is switch 1, the lamp that was off the whole time is switch 2, and the one that was on but turned off is switch 3.
