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.
6 C# T' t, _5 z! x* V公仔箱論壇: R9 i1 C& E! N" h- n
So the right hand side number 0 can be represented by number 1
+ f& @+ s3 s. z/ r4 K7 y5.39.217.77:8898The right hand side number 1 can be represented by 3,1,2,9,7,5
; i: ~# e) d9 d5 ~4 IThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
6 {1 D4 u- d! q, o( H+ {5.39.217.77:8898The right hand side number 3 can be represented by 5,9,8,3公仔箱論壇3 K, T% r6 a8 o! t# n1 X
The right hand side number 4 can be represented by 6( N& O, W. H) N& n, `
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! V. [9 M: H6 B
