Charles R Greathouse IV, Table of n, a(n) for n = 0..10000

FORMULA

a(n) ~ A007088(n). - Charles R Greathouse IV, Aug 09 2013

a(2^n + r) = a(2^n) + a(r) for 1 <= r <= 2^n - 1. - Peter Bala, Aug 12 2013

a(n) = A007088(n) - n. - Omar E. Pol, Aug 27 2013

EXAMPLE

5 in binary is written 101, so a(5) = 101-5 = 96.

MATHEMATICA

Table[d = IntegerDigits[n, 2]; FromDigits[d, 10] - n, {n, 50}] (* T. D. Noe, Aug 08 2013 *)

PROG

(PARI) a(n)=subst(Pol(binary(n)), 'x, 10)-n \\ Charles R Greathouse IV, Aug 09 2013

(MAGMA) [Seqint(Intseq((n), 2))-n: n in [0..50]];  // Vincenzo Librandi, Feb 20 2016
