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.
You can remove the character array object declaration and pass the character array object directly to the for loop. You can also delete the string object and return a string object by just calling the variables and concatenating with the '/' symbol in the middle and the string length at the end.
