Heaviest and Runner-Up

题目

You have 8 coins of pairwise-distinct weights and a balance scale that compares two single coins and tells you which is heavier. What is the minimum number of pairwise weighings, in the worst case, needed to identify BOTH the heaviest coin and the second-heaviest coin? (This is the classic tournament problem.)
