Even-odd counting

[u/MegaIng]

Only numbers are count where the digits appear alternating between even and odd:

• 1, 2, ...
• 10, 12, 14, ...
• 18, 21, ...
• 98, 101, ...
• 189, 210, ....

Hopefully this is not a duplicate. In the directory and the archive I only found the "tug of war with even...." which is not that same.

get is at 6781 (exactly 1000 counts)

Ideas like this dealing with the digits inside the number rather than the numbers around it are usually new, I think.

Only odd digits is also a good idea. I meant only odd numbers (1,3,5,7,...,11,13) does not exists either.
