There are 8 digits between the 1 of a(2) = 1 and the 1 of a(11) = 10: they are 2,3,4,5,6,7,8 and 9;
there is 1 digit between the 1 of a(11) = 10 and the first 1 of a(12) = 11: this is 0;
there is 0 digit between the first 1 of a(12) = 11 and the last 1 of a(12) = 11;
there are 2 digits between the last 1 of a(12) = 11 and the 1 of a(14) = 12: they are 2 and 0; etc.
All those gaps between successive 1s are distinct.
