There are three light bulbs on the second floor of a building and there are three switches on the ground floor which are used to turn on the light bulbs (one switch turns on one bulb).
A man is on the ground floor and he knows that the three light bulbs on the second floor are all turned off. How can he just goes up to the second floor ONCE to determine which switches control which light bulbs ??
