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.5.39.217.76  [: B2 s$ X* }6 C
公仔箱論壇: ?2 v4 E, Q9 F
So the right hand side number 0 can be represented by number 1 5.39.217.76( R; P9 L, g5 w- l, u* R7 X1 w5 x
The right hand side number 1 can be represented by 3,1,2,9,7,5
