Answer:
Drop the egg as many times as you want on any floor, as log as it is an inch above your foot or less, it will not break.
Explanation:
If a building has 200 floors, and you go to the top, you are at the highest floor. If you drop it from 1 inch above your foot it will not break, moving to any other floor on the building, so long as you follow the rule it will not break.
Or you can use a boiled egg :P
