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.

Great solution, using Streams as other solutions I think is overkill for this kata.
I suggest changing the type of result from String to StringBuilder to make it faster and less memory hungry for big Strings.

Finally the same solution I found is the top one! All of the other problems I solved had solutions by other people that were way better, lol. I did go with the StringBuilder as others have mentioned but the difference is kind of trivial. That would just be an efficiency upgraded needed when dealing with larger datasets.
