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

第一次称，两边6个，甘样肯定有一边会重D。跟住重D果6个分开两份每份3个称第二次。又系肯定有一边重D。剩低3个。抽其中两个称，如果重量相等，则没有被选中嘅球系最重的。如果重量不等，则重的那一边就是那个ball了

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
