8 Q$ V& W1 j; c公仔箱論壇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. 9 N* J' _; c; | M+ }) {6 i* F' t* G" _3 M; S. \1 q* ]
So the right hand side number 0 can be represented by number 1 5.39.217.77: T# e0 g) @' d% [5 A
The right hand side number 1 can be represented by 3,1,2,9,7,55.39.217.772 f$ ~) X" v5 u+ G
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0 : t9 _. f; H# JThe right hand side number 3 can be represented by 5,9,8,3 % p; i# o& p0 b5 e0 QThe right hand side number 4 can be represented by 69 A* A+ ^ a6 K
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2 + U P0 j- T. T( a8 |7 B8 x7 K. p公仔箱論壇 ) p% c+ ]8 ]. Q0 xSorry. My bad.
