You are a tax collector for a mad king. One day to test your ability to safeguard his income, he summons you to a challenge with your life at stake. Before you lie 14 gold coins gleaming and indistinguishable. The king tells you that one coin weighs an imperceptibly different amount and you must work out which coin it is! He offers to lend you his perfect balance scale but on the condition that on every occasion past the minimum number of uses you lose a finger.
How do you save your life while keeping your fingers?
