If I'm ever asked such a quesiton in an interview (fortunately, I never had that pleasure), I may answer with, "Before I answer that, I have a question for you. So, you're on this island, and you have two bottles and three nuts..."

LEDs are not perfectly cold after use.
The way to do it with LEDs would be turn the middle one on for a long time (let it heat), never turn on 1st one, turn on last one.
1st switch the light is cold, middle the light is warm, third the light is on.
