There is a building with 100 floors. You are given 2 identical eggs. How do you use 2 eggs to find the threshold floor, where the egg will definitely break from any floor above floor N, including floor N itself.? You have 2 eggs. You are on a 100 floor building. You drop the egg from a particular floor. It breaks or survives. If it survives you can throw the same egg from a higher floor. How many attempts do you need to identify the max floor at which the egg doesn't break when thrown down?
