then weigh B & C (B & C same weight)
  L0 p' ]* f, A) Hto find which group has the weight difference and find out is it (A is lighter)
0 r9 |+ e) ]+ j9 ?* Z4 Mheavier or lighter
$ G; i3 {1 ^" b$ hwww1.tvboxnow.comthen measure 2 vs 2 balls, EF vs GH, pick out the lighter group (EF lighter), R7 ~6 c. z! j+ j4 e4 D4 {

好難呀....
分成a,b,c三堆,分别为5,5,2三堆,先称a与b,若平衡,则中a中取一个与c中任一个称,就得到结果。若a与b不平衡,假设a略重,重a中随机取3个出来加上c中任一个,b中取3个出来加c中的任一个,若平衡,则a中剩余一个就为异常。若a仍重

哈哈

hv a look
