COMMENTS

Base 3 variant of A035327 (base 2) and A048379 (base 10).
See A256294  A256299 for bases 4 through 9, and A256303 for the variant where the result is not converted back to base 10.


LINKS

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


EXAMPLE

a(3) = 7 because 3 = 10[3] becomes 21[3] = 7.
a(8) = 0 because 8 = 22[3] becomes 00[3] = 0.


PROG
