A Megamind has 12 coins, one of which is counterfeit and weighs
differently from the others. He has a balance scale, but no weights.
How can the Megamind find the counterfeit coin and determine whether
it is lighter or heavier than the standard ones? What is the minimal
number of weighings required? |
