Jean-Marc Falcoz, Table of n, a(n) for n = 1..10001
EXAMPLE
Here are the first terms of the sequence:
1,10,12,2,13,4,15,6,7,3,8,9,5,11,14,16,...
and here are the cumulative sums:
1,11,23,25,38,42,57,63,70,73,81,90,95,106,120,136,...
If we align a(n) and its cumulative sum, we see that at least one digit is shared:
1,10,12, 2,13, 4,15, 6, 7, 3, 8, 9, 5, 11, 14, 16,...
1,11,23,25,38,42,57,63,70,73,81,90,95,106,120,136,...
