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.
А что если нет элемента в массиве?
Can't you make this one for loop, that then checks the 2 condition .
Do you really need to use "int length"?
Thanks
Just a small remark: it is not necessary to add the String.valueOf in the return statement.
