The next one describe the "21" as there are one "2" and one "1", therefore 12115.39.217.77:8898+ d) @; n4 U: Z+ V
The next one describe the "1211" as there are one "1", one "2" and two "1", so 111221. `5 L- Y) N) f. t' A
The next one describe this "111221" is three "1", two "2" and one "1" so the answer is: ; R5 e; S7 @6 F& k312211 0 \1 K2 T% F# c* ^( z! F; G5.39.217.77:8898' p/ {' ]# t: ?5 J% t" r

tvb now,tvbnow,bttvb8 \+ V5 ~5 |2 U6 @1 @: ?
So the right hand side number 0 can be represented by number 1 5.39.217.77:8898- Y3 _0 b/ D4 g' @4 M; u* L
The right hand side number 1 can be represented by 3,1,2,9,7,5 # @5 t6 H, f4 ?- SThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0 . z( k3 t) q( N! {.

Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2 9 j/ Y9 z.
