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.tvb now,tvbnow,bttvb% w+ q0 w9 W f& L* G' Y! D+ Y

So the right hand side number 0 can be represented by number 1 / t4 c% S; n1 x0 Q9 _# D公仔箱論壇The right hand side number 1 can be represented by 3,1,2,9,7,5+ c: o; _( F' d- F2 p/ [ M' \
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0 ' a& r( @" g$ Z) W( B( iThe right hand side number 3 can be represented by 5,9,8,3 5 F& _" F! ~; @3 ~7 j( A5.39.217.77:8898The right hand side number 4 can be represented by 6: R' S; R+ Z$ b$ J
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2 % I% x E" n8 P1 Jtvb now,tvbnow,bttvb 1 g' S# J5 }! ^6 {Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. 9 E9 x5 C5 V- A% m1 \$ k! g" r. l" o
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.5.39.217.77:88988 S8 L6 ]1 g* X$ o
