This week's extra credit Problem Of the Week.

P.O.W. #4

A downstairs panel contains three on-off switches,

one of which controls the lamp in the attic.

But which one?

Your mission is to do something with the switches,

then determine, after only one trip to the attic,

which switch is connected to the attic lamp.


Last week's answer:

The highest answer, so far, is 31.  Unless you made your line so thick that it went through all of the numbers.
