COMMENTS

Base 9 variant of A256078 (base 2) and A048379 (base 10). See A256303 - A256308 for bases 3 through 8, and A256299 for the variant where the result is converted back to base 10.

LINKS

Table of n, a(n) for n=0..59.

EXAMPLE

a(9) = 21 because 9 = "10" in base 9 becomes "21".

a(80) = 0 because 80 = "88" in base 9 becomes "00".

PROG

(PARI) A256289(n, b=9)=!n+eval(Strchr(apply(d->(d+1)%b+48, digits(n, b))))
