COMMENTS

Base 3 variant of A256078 (base 2) and A048379 (base 10). See A256304  A256308 for bases 4 through 8, A256289 for base 9, and A256293 for the variant where the result is converted back to base 10.


LINKS

Table of n, a(n) for n=0..51.


EXAMPLE

a(3) = 21 because 3 = "10" (in base 3) becomes "21".
a(8) = 0 because 8 = "22" (in base 3) becomes "00".


PROG

(PARI) A256303(n, b=3)=!n+eval(Strchr(apply(d>(d+1)%b+48, digits(n, b))))
