Programs

Scheme

(define (A292262 n) (A007949 (+ 1 (A245612 n))))
(define (A292262 n) (A007814 (+ 1 (A291763 n))))
(define (A292262 n) (cond ((<= n 1) n) ((odd? n) 0) (else (+ 1 (A292261 (/ n 2))))))

Formula

a(n) = A007949(1+A245612(n)).

a(n) = A007814(1+A291763(n)).

a(0) = 0, a(1) = 1, after which a(2n) = 1 + A292261(n/2), a(2n+1) = 0.
