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.

This description is incredibly unclear.
How are we supposed to know if the input string can be split into single digits or two digits or not split at all?
"123" -> [1, 2, 3] -> 1
"1234567891" -> [1234567891] -> 1234567891
There's no explanation of why the two examples above are being split up differently.
