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.
I'm having the same problem you did, how exactly did you resolve yours again?
Yes I got stuck because I tried to use stream. I am not sure how to make each value unique
This kata is perfectly solvable with integers, so if your solution uses floating point numbers at any point, it can be probably improved.
n ** 2 == n * nwhat's the problem? It's not missing, it used the latter.Thanks!
