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.
Description requires to round to the nearest integer, but this is actually not tested, with the few tested values the exact result is an integer, which makes this specification pointless.
No random tests. Only three fixed ones. Please refer to the documentation about authoring katas: https://docs.codewars.com/authoring
