%N The smallest n-digit number whose last k digits are divisible by k for k = 1..n.
%e There are ten one-digit numbers divisible by 1, and the smallest is 0, so a(1) = 0.
%e For two-digit numbers, the ones digit must be divisible by 2 which gives 10 as the smallest to satisfy the requirement. So a(2) = 10.
%Y Cf. A164836.
