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.

Test fails:
For example this shouldn't output "VISA":
4111111111111111
4111111111111
4012888888881881
41111111111111
411111111111111
But the definition says, it's VISA
Typescript test cases fail. Please correct the tests. My code works.
in my case i had to replace "\n" (new line) in Java at the beginning of the string.
