A210414 List the positions of all digits 0 in the concatenation of all terms, not necessarily in order. This is the lexicographically earliest such sequence.

3, 10, 6, 20, 9, 100, 14, 30, 18, 40, 50, 24, 60, 28, 70, 80, 34, 90, 38, 1000, 39, 46, 101, 110, 54, 102, 59, 200, 64, 103, 69, 300, 74, 104, 79, 400, 84, 105, 89, 500, 94, 106, 99, 100000000, 1010, 108, 112, 121, 201, 127, 202, 133, 203, 139, 204, 145, 205, 151

Examples

			The sequence cannot start with 0 (offset starting from 1), 1 (in the first position we have 1, not 0) or 2 (the second entry cannot start with 0). So the sequence starts with 3. The next term is 10, which is the minimum number with 0 as its second digit. And so on.
