%N Odd bisection of the infinite Fibonacci word A003849.
%F a(n) = 2 - [(2n+3)r] - [(2n+2)r], where [ ] = floor and r = golden ratio (A001622).
%e A003849 = (0, 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 0,.. ), so that
%e A339824 = (0, 0, 1, 1, 0, 0, 1,...), the even bisection.
%e A339825 = (1, 0, 0, 0, 1, 0, 0,...), the odd bisection.
%t r = (1 + Sqrt[5])/2; z = 300;
%t f[n_] := 2 - Floor[(n + 2) r] + Floor[(n + 1) r]; (*A003849*)
%t Table[2 - Floor[(2 n + 2) r] + Floor[(2 n + 1) r], {n, 0, Floor[z/2]}] (*A339824 *)
