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! G( V: ]# r3 z$ F" S) X
2 v/ o& z+ q: X& G3 G5 |9 a/ Mwww2.tvboxnow.comSo the right hand side number 0 can be represented by number 1 # t8 K3 m4 e4 Y2 M: M) O, r. ~
The right hand side number 1 can be represented by 3,1,2,9,7,5
4 r4 \" @+ Z$ {" a3 Gwww2.tvboxnow.comThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
4 j9 U  N% y) g; U& N1 e; z2 eThe right hand side number 3 can be represented by 5,9,8,3www2.tvboxnow.com# b# \- K. e% b8 I5 Z/ _- t. e3 }& c
The right hand side number 4 can be represented by 6
& V9 H0 {! X) @# uwww2.tvboxnow.comNow the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2tvb now,tvbnow,bttvb  g3 S9 i- H3 ?

$ l4 _+ J7 J0 t% f/ H* qwww2.tvboxnow.comSorry. My bad. Someone told me that it is actually counting the number of holes in the given number.
