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.

Yes.
ohhhh that makes so much more sense now. so just add up all the entries of the inner lists that have the same index (so list1[0] is added to list2[0] and so on)? am i understanding this right?
Check the based on part. It's the first element of the first inner list plus the first element of the second inner list, and so on.
i kinda don't understand the question. it's worded weirdly, but i can kind of guess what it wants me to do.
and the maths seems to be off. for the input [[1, 5, 7, 1], [1, 7], [6], [], [7, 1, 8, 2, 9]], the output should be [15, 13, 15, 3, 9]. however, 1+5+7+1 = 14, not 15. 1+7 is clearly not equal to 13, 6 != 15, etc. the question is quite vague, so i don't really know how to return the output.
