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.
Random tests added, tabs fixed.
Tabs in the python version conflicts with codewars editor (it uses 4 spaces)
There needs to be more test cases given, at least one for each of the edge cases outlined in the desc. (n < 0, n == 0). some random test cases would probably be good too
