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.

Yep, it's my mistake.
Thanks!
Instruction says that: If str longer than 140 characters! But, there is a test case with parameter: 'a'.repeat(140);
Wrong instructions or test case!!!
I like it! It would be great if resturn is: return !parens;
