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.

Thanks foe answer! Kata complite)
i understood this time. the input was actually null. i got it thenk you for helping.
printing also says "null". cant't understand what this means.
It's a question: a problem in your code is not a kata issue.
You can print the input.
whats wrong with it. passes all the tests except one which says "can't read property length of null". not showing the input for which this error is appearing.
It would be wrong.
