There is a 100-story building and you are given two eggs. The eggs (and the building) have an interesting property that if you throw the egg from a floor number less than X, it will not break. And it will always brake if the floor number is equal or greater than X. Assuming that you can reuse the eggs which didn't broke; you got to find X in a minimal number of throws. Give an algorithm to find X in minimal number of throws.
