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.
Since the kata wants us to return a list, it doesn't matter. It would matter if the kata wanted us to modify the list in place though.
Hi there guys :D, first of all, thanks so much for this opportunity and the exercises that you provide on this site as well...
Don't know if I'm satisfied as the code that I've proposed in my python solution doesn't eliminates/deletes the elements but it ignore these, so it's basically not that accurate or it doesn't respects the instructions itself but it has been approved... Doesn't know if this is like "It works man, just chill" thing...
