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.
Yes it is, I'm sorry. I missread some parts. I've changed it, now it works. Very fun kata, thank you!
I tried your solution and it always return "undefined". Something is wrong in your code.
When I test my solitin in VS code with your examples; all works. When I attempt it here on codewars, it returns: error; expected 'NJVGhr\nMObsvw\ntPhCtl\nsoEnhi\nrtQRLK\nzjliWg' instead got undefined. And I even tried a matrix of 20x20 with symbols and numbers in it, and still works in VS code. Can you figure out what is wrong? Thanks
