i find one solution that is similar! l6 s7 \, y/ E2 X
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....# i3 S+ q4 ]+ d) H6 Z4 Q
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...
