Hey guys, here's a puzzle for you
There are three switches downstairs. Each corresponds to
one of the three light bulbs in the attic. You can turn the
switches on and off and leave them in any position.
How would you identify which switch corresponds to which
light bulb, if you are only allowed one trip upstairs?
