COMMENTS
Starting with another "seed" than 0 would produce another sequence.
EXAMPLE
After 19 we must have an integer containing an "8" (1+"8"=9) or a "0" (9+"0"=9). The smallest available such integer is 30 (0 is not available, nor 8, 10, 18, 20 and 28 -- all of those containing either a "0" or an "8")
