EXAMPLE

As a word, A003849 = 0100101001001010010100100..., and replacing each 0 by 01 and each 1 by 10 gives 01100101100110010110010110011001...

MATHEMATICA

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

w = StringJoin[Map[ToString, s]]

w1 = StringReplace[w, {"0" -> "01", "1" -> "10"}]   (*Thue-Morse transform*)

st = ToCharacterCode[w1] - 48    (*A287657*)

Flatten[Position[st, 0]]  (*A287658*)

Flatten[Position[st, 1]]  (*A287659*)
