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.

import Data.Char
digits :: Integer -> [Int]
digits n = (map digitToInt).show n
although it seems useless to convert char to int since char itself can be sorted.
