because the "list" function works with strings, but not with numbers

In fact cannot be smaller than 1, not 0. So should be "<= 0", due if in a test you pass a 0º angle it won't enter to the first condition but give you a result anyway, but an angle can't be 0, this is a line, right?

I think because the join() function requires it to be a string.

|| - old and bad solution, need ?? - best and clever.

This is what I ended up with, I massively over-complicated it, shows that reading the description very carefully helps!

This is n log(n) time complexity. can't we simply do O(n) without sorting?

that's not really necessary, seeing how it was stated that only positive number would be given...

every time i look answers like this i learn something

i agree with that

last lines should be:
s = int(s)
return s

I like that imperative-style coding)

thanks always thought there must be a better way than comparing values before and after typeconversion
