You shouldn't use input on Codewars in general. A number will be fed to your function in the tests. Just assume that function will receive the necessary parameters to execute without having the user entering any kind of number. Hope this helps! If you reset your solution, you should use "n" as the number who will be necessary to code your solution.

Very cool kata! The indications on how you expect the values to be sorted could be a tad bit clearer though!

Completely agree and especially since all the sample tests follow this logic... Would it be possible to either make it clear in the instructions or to include a sample test which makes people understand the string might be a bit more complex than an alphabetical string followed by a numerical string?
