6 W9 B( ?" L- R3 d- z公仔箱論壇" z& t' y' [5 Q0 o& |& n" Z
So the right hand side number 0 can be represented by number 1 www2.tvboxnow.com6 t. V3 m. ^5 X- S( M2 K0 ?4 V/ y
The right hand side number 1 can be represented by 3,1,2,9,7,5
8 R2 B+ K, S0 U( ^/ [) v5 D8 UThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
6 O- S3 c' E- V+ @7 S  DThe right hand side number 3 can be represented by 5,9,8,30 i# d. O5 ]+ E2 A6 i) I
The right hand side number 4 can be represented by 6
; ~% D- I: V6 t- a. \www2.tvboxnow.comNow the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2
