Ready for the solution? Click here to see if you’re right. You might want to try solving for the case of 10 unlabeled circuit breakers first. The solution does not involve either switching on or off the light switches in your house or feeling how hot the lightbulbs are. What is the minimum number of trips you need to make to the basement to map every circuit breaker to every light? Hint You can then roam the hallways of your house to discover which lights are on and which are off. On every trip to your basement, you can switch any number of circuit breakers on or off. To start with, you switch all 100 lights in the house to “on,” and then you head down to your basement to begin the onerous mapping process. (Suppose each circuit breaker maps to only one light.) To your chagrin, you discover none of the 100 circuit breakers is labeled, and you face the daunting prospect of matching each circuit breaker to its respective light. The circuit breaker box in your new house is in an inconvenient corner of your basement.
