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.
; p3 f% E( f/ ^. z) [
/ o. m: v( i$ a' W, Q9 o7 iSo the right hand side number 0 can be represented by number 1
: s( t) X* a/ S. Ftvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5! H, {: D0 i# b+ C4 w* g2 j! T1 k
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0

Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2公仔箱論壇- O( o& y4 C; V: k' R  K+ v, O

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. ! }$ @, _- f; s" ~. a+ S6 [" ]) d7 G9 O
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
