Wangapi wanaeza nipatia jibu.......???? In your basement are three light switches, all of them currently in the OFF position. Each switch controls one of three different lamps on the floor above. You would like to find out which light switch corresponds to which lamp. You may move turn on any of the switches any number of times, but you may only go upstairs to inspect the lamps just once. How can you determine the switch for each lamp with just one trip upstairs?
