先6/6 得出一边重一边轻,然后3/3 分2组,因为异常的只有一个球,所以得出其中一组3/3是等重的.反之另一组是有异常的. 在正常的取一个出来,得出4个,然后2/2  1/1 出结果

4 vs 4, two case => a)same or b)diff.
. F5 |3 G# Q2 D& [9 D- h# r7 j7 Va)the not weighted 4 have the target, take 3 to weight with normal => same=the forth is target, diff. can let us know the target is heavy or light, weight two of those contain the target will let us know the answer  
. I: ^: [: L+ L8 X. R: Ib)diff. result will have light and heavy again 4vs 4, C vs D C=(3 normal + 1 heavy), D=(3 heavy + 1 light) => again 2 case same or diff., For diff. if C is heavier, than the target is that put in C, if D heavy, the 3 heavy can be weighted with 1 vs 1, heavy one is the target... For same, the target is in that 3 lighter ones, weight them 1 vs 1 will let u know the answer...

12球分两组后，重的一边 两个一组分三组，同时放上两组，如果天平平衡说明在没称重的那两个球里，然后把那连个球一边一个。马上出来，三步！如果在开始放的两组里面，把重的一组拿下来，一边一个，及的答案，也是三步
