i find one solution that is similar: T+ t3 n4 ]8 }: r2 K
but i can't specify the heavier one is abnormal or the lighter one is abnormal when the case that has only two balls left....& |3 S7 W- V7 b: r7 T, C! e, y
maybe there is a better one, let me see sin
actually this question always have someone asked, the calculation is very complicated, should give a no. of each ball, and first weight it in 6-6, and .... forgot...
