在 39 枚金幣中找假幣
公式解
將硬幣編號 1,2,3,...,39
不論前幾次稱如何,均按照下面的編號來放置四次稱法
一 1 3 5 7 9 11 13 15 17 19 21 23 27 對 2 4 6 8 10 12 14 16 18 20 22 24 26
二 1 3 5 7 9 20 22 24 26 29 31 33 35 對 2 4 6 8 19 21 23 27 28 30 32 34 36
三 1 3 8 11 16 18 19 21 26 29 36 37 39 對 2 7 9 10 12 17 20 22 27 28 30 35 38
四 1 6 7 12 13 18 19 22 25 30 31 36 37 對 3 4 9 10 15 16 21 24 27 28 33 34 39
每次左輕記為 0,平衡記為 1,右輕記為 2
