EXAMPLE

As a word, A003849 = 0100101001001010010100100..., and replacing each 0 by 1 and each 1 by 011 gives 10111101110111101111011101111011101111011110...

MATHEMATICA

s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {0}}] &, {0}, 10] (* A003849 *)

w = StringJoin[Map[ToString, s]]

w1 = StringReplace[w, {"0" -> "1", "1" -> "011"}]

st = ToCharacterCode[w1] - 48    (* A287725 *)

Flatten[Position[st, 0]]  (* A287726 *)

Flatten[Position[st, 1]]  (* A287727 *)
