逐粒放，一边一粒，有两种情况，www3.tvboxnow.com4 c1 K& N% E- Y8 d- W- S
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www3.tvboxnow.com' m' q2 f" I4 Y/ L6 c/ b; @
第二种：1.第一同第二粒重量一样，继续加，加到个天平倾斜为止（前提係两边波既数量要一样），最后放落去果粒或倒数第二粒就係异常2.重复第一种情况第2步

將乒乓球分4份,每份3個.www3.tvboxnow.com5 T% I; A6 i$ d: h7 s# `5 L
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）7 E1 u( m7 o: F; t" R3 E/ C
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.

3/. Pick 2 balls and put them on each side from the remaing 3 balls. If they are equal weight, the ball on the table is the more heavy one, if one side is more heavy than the other, that will be the more heavy one.

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。
