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.
Please use appropriate datatypes. String is very rarely an appropriate datatype, and it isn't here either.
No random tests...
There is no information on how to process non-numeric strings (like
"fiv") in the tests: it seems we're supposed to ignore them from the sum.
