# S* O3 V2 Q; |/ G8 o$ x* E3 M5.39.217.77:8898After 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.. ~2 i5 D5 d; g2 w

) ~% ^1 j7 Z5 D. l. ~公仔箱論壇So the right hand side number 0 can be represented by number 1 公仔箱論壇6 s9 P6 \% q1 `  o% e; ]9 |! B
The right hand side number 1 can be represented by 3,1,2,9,7,5
2 p8 |3 q0 I) z# A9 ^! G$ r5 A5.39.217.77:8898The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0

The right hand side number 4 can be represented by 66 w: c7 X0 J! E9 S; |0 ]* _1 z
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2
