Answer 2

It seems like you've entered a sequence of numbers separated by a colon, followed by "столбиком," which means "in a column" in Russian. It's not entirely clear what you're asking or referring to with this input.

If you could provide more context or clarify your question, I'd be happy to assist you further.
