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.

OP solved it, closing
I'm not sure whether I understand your first question. Your function takes as arguments an array and its length. You can safely access every element of the array from
0tolength - 1.You do not need to (and should not) alter the given
array(this is why it is marked asconst: it is a constant ). You need to return a singleint, that is the sum of all the unique array elements.
