Tuesday Teaser #5
I’m in a building with 20 floors and I have two laptops. I want to know the highest floor from which I can drop a laptop without it breaking. For the purposes of the puzzle, the laptop either breaks or works after each drop. Obviously after a laptop breaks, it can no longer be used, so I’m down to one. What is the least number of drops needed to identify the maximum height?
