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.
I'm sorry, just noticed there is mistake in my code
In which dimension is a negative integer greater than zero? It's so normal that the author didn't even indicate this in kata description?
lol
wow
thanks to g964 for the most stupid waste of my time i dont remember since when
loooooooooooooooooooooooooooooooooool
I get a TypeError: Cannot read property 'length' of null
But in the first line of my function there is a check: if (str === null) return false;
If the input is null, why it doesn't return false and the code continues to run next?
