Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

I´m a beginner and this was my solution :)
please, asking for help is not a kata issue, ask a question instead and format your code correctly: https://docs.codewars.com/training/troubleshooting/#post-discourse
your line
num - 1
has no effect. it computesnum - 1
and then discards the result, this is why your code never ends, sincenum
never changes.num = num - 1
akanum -= 1
would ensure thatnum
is decrementedThis comment is hidden because it contains spoiler information about the solution
