逐粒放，一边一粒，有两种情况，' {0 R8 G* \$ \5 f% N( Y7 T
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）
( c1 e8 l; m2 P5 B7 m0 B( {' i2 ]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.

It says find the 1 ball  weights different from the other 11 balls, NOT FIND THE HEAVIER BALL.  Read the question before try to be a smart ass.

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。
