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.
From the description: "When an array in the array is null or empty, the method should return 0 too!"
So 0 is correct.
For java the answer is wrong, the answer of the following question should be 2 not 0!
Wrong for [[1, 0, 3], [1, 1, 1, 1, 4], [4], [3, 2, 0, 2], []] expected:<0> but was:<2>
no matter how long the number, just need 10 loop
