" B- J1 U" p2 z+ n) ~( }* ]4 k1 wAfter 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.5.39.217.77:88987 R7 K9 R( s5 m) c3 P
: x( G C* x0 bSo the right hand side number 0 can be represented by number 1 1 O, K: R' }0 E2 w0 \6 U
The right hand side number 1 can be represented by 3,1,2,9,7,5 : r$ Y- u% o" j5 c公仔箱論壇The right hand side number 2 can be represented by 2,5,8,1,6,7,3,05.39.217.77:8898% J# U+ ^# a# l
The right hand side number 3 can be represented by 5,9,8,3 3 e4 s. H8 X& T# y( x2 d" XThe right hand side number 4 can be represented by 6tvb now,tvbnow,bttvb/ ?* Q5 F- e+ w( B9 @; c0 i' \$ e
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2 " H9 [/ U8 K- r. T+ |6 I+ |: J$ ]5.39.217.77:88985.39.217.77:88980 q9 H4 t/ P9 X% [0 e% y
Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. 公仔箱論壇, b% j, G* X+ O3 m) e
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3. o4 M8 `! _/ {# h% stvb now,tvbnow,bttvb t& K! r& H/ w) G! i5.39.217.77:88986 t! K5 S0 U3 i+ V4 o- b) D
