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.

i wonder where to find a parentheses in here: 'hello example here something' should equal
and i don't understand why the output is like this: 'hello example something'
it looks for me that the function is only deleting -here - in the string, that does not make any sence to me, since the description is talking about remove parentheses and the content inside them....
