The sequence can be seen as a succession of digitchunks ending in "1". The digitsize of each chunk is given by the sequence itself. No term is repeated. This is the lexically first sequence with the property.


1



1, 2, 10, 3, 4, 5, 6, 7, 8, 9, 21, 20, 12, 22, 13, 23, 31, 24, 25, 41, 26, 27, 28, 14, 29, 30, 32, 15, 33, 34, 35, 51, 36, 37, 38, 39, 40, 42, 43, 44, 45, 46, 16, 47, 48, 49, 50, 52, 53, 54, 55, 56, 17

COMMENTS

All integers appear in the sequence, except the ones that have two or more consecutive 1's (like 11,110,111,112,113,...).


LINKS

Table of n, a(n) for n=1..53.


EXAMPLE

If we put a vertical stroke right after each "1", the sequence becomes:
12,10,3,4,5,6,7,8,9,2120,12,22,13,23,3124,25,4126,27,28,14,29,30,32,15... Now count the digits between two strokes: you'll get 1,2,10,3,4,5,6,7,8,... which is the sequence itself.
