I've one puzzle here. Here it goes. Lets say you have 2 eggs (kukhurako anda :)) and a 100 story building. The egg will only break when you drop them from a particular floor and above. Now, you need to find out that edge floor number after which egg will be broken if dropped in least number of iterations. You can fetch the egg if it's not broken after being dropped. For eg. if you start dropping an egg from floor 1, if it doesn't break then you drop it from floor 2 .....and then floor 3 and at last if it breaks after dropping from floor 33 then the edge floor number is 33. But in this example solution, it took 33 iterations. Anyone who gives the answer with least number of iterations win. Thanks and good luck. I have another puzzle in waiting too. First, lets solve this one.
