逐粒放,一边一粒,有两种情况,
6 \/ @$ m! k( n% u# B* q公仔箱論壇第一种:1.放完第一同第二粒时,天平已经倾斜咗,即係其中一粒係异常,2.攞起任意一粒,将剩低果粒同第三粒比

將乒乓球分4份,每份3個.公仔箱論壇$ I$ d7 n$ N% H4 s
將其中一份與其他兩份分別稱兩次可得出一份重量異常.(重/轻)
3 X9 w% r, h- p# h抽其中两个称,如果重量相等,则没有被选中嘅球系最重/輕的。如果重量不等,则重/輕的那一边就是那个ball了

FIRST PLACE 6 BALLS ON EACH SIDE OF THE LIBRA. ONE SIDE MUST BE HEAVIER THAN THE OTHER IF ONE OF THE BALL WEIGHT MORE. NOW WITH 6 BALLS LEFT, PLACE 3 BALLS ON EACH SIDE OF THE LIBRA. THE WEIGHT DIFFERENCE WILL ELIMINATE 3 MORE BALLS. WITH 3 BALLS LEFT, JUST PICK 2 BALLS AND PLACE THEM ON THE LIBRA. IF THE WEIGHT ARE THE SMAE. THEN THE BALL NOT ON LIBRA WILL BE THE HEAVIER BALL.

先把12 分为 4組每組3个, 先把1組同2組称, 3组同4组称.最后,把差别最大的再称抽其中两个称,如果重量相等,则没有被选中嘅球系重量異常的。
