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.

Wow :o
like 'Afri_a' is so concise. I'm gonna implement it on my daily basis.
Thanks.
Maybe I didn't understand the goal of the exercise...
Can you explain me what's the meaning of the rest of the rows?
It's supposed you have to return only the sum of all the goals, so just one row...
And what's the issue with this?
I think it's not working in SQL.
Test: expected return 2 rows: 0 and 58 (the right result).
Submit: expected return 100 rows (¿?)
