逐粒放，一边一粒，有两种情况，- A4 G# F8 O2 B8 t) K* r
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tvb now,tvbnow,bttvb. J9 x7 w  s2 h, v- \4 u
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

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。
