%N a(0) = 0, and for any n > 0, let k > 0 be as small as possible and such that F(2) + ... + F(1+k) >= n (where F(m) denotes A000045(m), the m-th Fibonacci number); a(n) = k + a(F(2) + ... + F(1+k) - n).
%C See A095791 for the corresponding k's.
%C This sequence has similarities with A227192; here we use Fibonacci numbers, there powers of 2.
