E; f2 e# F5.39.217.77:8898After 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. 0 [& {1 Z4 j; a2 _$ }0 E. b9 l& _( N
So the right hand side number 0 can be represented by number 1 " k3 k) f, G* k% |tvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5 1 [/ d/ Y) \0 @8 W5.39.217.77:8898The right hand side number 2 can be represented by 2,5,8,1,6,7,3,05.39.217.77:8898' ~7 g& w2 S: T5 d
The right hand side number 3 can be represented by 5,9,8,37 x" G; ~) ^" }6 i6 ^
The right hand side number 4 can be represented by 6 {# [% C5 N2 F0 }; t8 _
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2 M4 _+ C2 S A ~1 E( d % z- l6 S- c8 S# p3 }1 C, [3 O公仔箱論壇Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. tvb now,tvbnow,bttvb: a" [ z4 Z9 n+ w
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3. : M! G' {, P7 W4 c6 b' t% _: j- }5.39.217.77:88982 M$ Y& q! v$ ]8 z( X
