(由 Microsoft 翻譯) 當在39枚硬幣,把13枚硬幣放在一邊,13枚硬幣在另一邊。

1. 如果雙方相等,遊戲是不可能的,你必須刷新。
2. 如果一側較重,另一側較輕,則可溶解:

1. 如果雙方相等,這意味著收起來的9枚重硬幣之一是假的。將其中3個放在一邊,將其中3個放在另一側。如果一邊更重,假幣就在那裡,如果兩邊相等,假幣就不在那裡。然後把一方的假嫌疑人放在一邊,一邊放在一邊。
2. 如果 A 面較重,則意味著 A 面的 4 枚硬幣可能是假的(較重),B 面的 4 枚硬幣可能是假的(較輕)。在一側,一個較重的假犯罪嫌疑人和3個較輕的假犯罪嫌疑人,B面的1名較輕的假犯罪嫌疑人和3名好幣。

(原文) Coin Weighing

When in 39 coins, put 13 coins in one side and 13 coins in another.

1. If the two sides are equal, the game is impossible and you have to refresh.
2. If one side is heavier and the other is lighter, it is solvable:
Move 9 coins from the lighter side to the heavier side, move 9 of the coins from the heavier side away, and put 9 of the other coins to the lighter side. The heavier side becomes side A, and the lighter side becomes side B.
1. If the two sides are equal, this means one of the 9 heavier coins put away is fake. Place 3 of them on one side and 3 of them on the other. If one side is heavier the fake coin is there, if the two sides are equal the fake coin isn't there. Then place 1 of the fake suspects on one side and 1 on the other.
2. If side A is heavier, this means that either the 4 coins in side A may be fake (heavier) or the 4 coins in side B may be fake (lighter). On side A place 1 of the heavier fake suspects and 3 of the lighter fake suspects, on side B place 1 of the lighter fake suspects and 3 good coins.
