How to crack floor arrangement puzzles faster
- Floor puzzles are vertical rows — treat floor 1 as "leftmost" and floor N as "rightmost" in your mental model.
- "Lives above" means a higher floor number. "Immediately above" means exactly one floor apart.
- "Exactly k floors between" gives a fixed vertical gap — try it at each valid pair of floors.
- Write the floor numbers 1 to N on paper and fill names as you lock positions — the visual stack prevents errors.
