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.
Oh, okay
Duplicate of the kata you linked. The difference is too small to be worth of another kata.
Thank you for your comment
Tests fixed
However, please tell me a duplicate of what?
test.assert_equals(sum_n_arrays([1,2,5],[1,2]),[1,3,6])- should be [1, 3, 7]
