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.
- S, _0 N  c. E5 y  N; ]
7 c2 p* p- R  u/ ~$ M) u% J1 uSo the right hand side number 0 can be represented by number 1
& {) m' }4 l+ U7 b$ M* n4 ?* k% Wtvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5tvb now,tvbnow,bttvb& F2 f" c/ V4 K8 x+ {, L0 y
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
! L& G6 ~7 {8 Z  M公仔箱論壇The right hand side number 3 can be represented by 5,9,8,3公仔箱論壇8 y5 I- ]+ x7 D- x1 ]: j
