Puzzle: You have two eggs and a 100-floor building. You want to find the highest floor from which an egg can be dropped without breaking. What is the minimum number of drops needed?
Answer: 14 drops are required. Drop the first egg from floors 14, 27, 39, …, and so on. If it breaks, use the second egg to test each floor sequentially from the last safe floor. This ensures a minimal worst-case scenario.
