Among 101 coins, exactly 50 are counterfeit. A counterfeit coins
weighs one gram more or gram less than the real coin (counterfeit
coins may weigh differently). You have a balance scale that shows the
exact weight differential between the two cups. How can you
determine whether a given coin from this set is counterfeit using the
scale only once? |
