After seeing the IQ question 據說這是蘋果公司的面試題, it reminds me of grouping the left hand side numbers to reflect the number on the right.tvb now,tvbnow,bttvb- b# g& s$ _( O. m4 Q' H

' f9 l$ @4 P- j  C* `3 dSo the right hand side number 0 can be represented by number 1

The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
