! T( j' T- `+ w: J9 X1 _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.公仔箱論壇7 d3 Z, E4 V" _7 o
4 i  G$ [# U( |; V7 E
So the right hand side number 0 can be represented by number 1 8 E) r5 A( G6 w0 {+ }: X, u7 B
The right hand side number 1 can be represented by 3,1,2,9,7,5
; u& x4 ^* h8 Itvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. 公仔箱論壇" r3 Q0 _8 J8 q$ L4 S5 G" m& G
