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. : r0 X! G. Q4 {: B5 k$ b' q; h公仔箱論壇; T- w# X% @5 r- M: n n
So the right hand side number 0 can be represented by number 1 + ?/ }0 o( i; i7 |The right hand side number 1 can be represented by 3,1,2,9,7,5 2 t7 i% k- t8 d!

The right hand side number 4 can be represented by 61 L2 w' A( d- M
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2 * Y9 S# {: r!
