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. 8 I2 }( A$ R/ z! q$ j) t% N' a( ~! etvb now,tvbnow,bttvb# T8 ?7 x, `3 Y$ `5 @" g$ A- A
So the right hand side number 0 can be represented by number 1 1 o D!

Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2tvb now,tvbnow,bttvb( N& z* }- v8 `
