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.
) W; F) f: n5 m4 ^" f5 \. ~; @$ t5 R3 [5 M" V& ?; j; i
So the right hand side number 0 can be represented by number 1 ! A8 u  d( d$ L
The right hand side number 1 can be represented by 3,1,2,9,7,5
/ |% L' S5 T8 Ytvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
