Thanks for the reply. I honestly don't remember ever hearing of people thinking 0 would be an odd number. I suppose there could be a question around it for people new to math and coding. But yeah, if it needs to be clarified, they might as well go ahead and list all the odd digits.

No worries. I mean, it's not wrong... 0 of course shouldn't be counted as an odd digit. Just a bit humorous.

Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.

"Don't count zero as an odd digit."

Just curious, why does this need to be said?

Cleaner than the top rated solution

That's not a valid argument for this problem. Only one number can be different.

this is the way

cool 8kyu kata, and solvable by looking at the example, but the description doesn't make sense. We aren't removing any spaces.

How do you comprehend this?
Maybe I need to study recursion more, but it's too hard to follow.

Yeah in JS yesterday it took me about an hour to get it working, but way too slow! Still haven't been able to improve it. May need to start over.

At least 1234567, which my solution currently can't solve within the time cosntraints here.

I don't understand how this passed the requirements.
