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.
, ^" Q9 h4 y8 J7 Y$ m7 q+ ftvb now,tvbnow,bttvb
* Q' o. A7 V; P5 v& x公仔箱論壇So the right hand side number 0 can be represented by number 1 * v9 n- ^' d: k& a  x1 D
The right hand side number 1 can be represented by 3,1,2,9,7,5
% s( I( r; N% `: N4 N  j5.39.217.76The right hand side number 2 can be represented by 2,5,8,1,6,7,3,04 E- [/ S8 E7 b1 q- `
The right hand side number 3 can be represented by 5,9,8,3
$ X, S; M) {+ [/ Ltvb now,tvbnow,bttvbThe right hand side number 4 can be represented by 6公仔箱論壇' ]( N- C# b) K" W. m
