" D9 q9 z2 N" c. H1 L
So the right hand side number 0 can be represented by number 1 tvb now,tvbnow,bttvb4 d- V) q% x1 C2 Q+ }' R* G
The right hand side number 1 can be represented by 3,1,2,9,7,5
5 }9 c. k; ~. j  @4 ctvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0tvb now,tvbnow,bttvb6 H. Z: Z9 T7 ~1 l/ k5 ^4 p. p# d
The right hand side number 3 can be represented by 5,9,8,3

6 B/ h% A, N+ O3 e. B, Y  B1 ?  JSorry. My bad. Someone told me that it is actually counting the number of holes in the given number.
