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.- d% N- j+ C% P  u* m, ~

- n1 P. T8 C4 Q4 N2 `- y. Z% M; a' Ptvb now,tvbnow,bttvbSo the right hand side number 0 can be represented by number 1
0 Z/ M) k& f8 d: ^( y" FThe right hand side number 1 can be represented by 3,1,2,9,7,5
# X. K. c" C3 b3 h7 Utvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
+ i, ~/ _) X# Z, ?2 b$ k- PThe right hand side number 3 can be represented by 5,9,8,3

- Q1 v1 Y( K8 ~: `5 H% ~2 \Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2- O0 |, ^% v/ ]2 X, Z
