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.
Expected string length 15 but was 16. Strings differ at index 11.
Expected: "###########5616"
But was: "############5616"
Assert.AreEqual(Kata.Maskify("4556364607935616"), "############5616");
What?
Are you using the usings?
I can't seem to be able to use Arrays, is there something I have to do diferently in codewars?
It is also not a good solution.
Yes there is. You must use System.Math instead of just math.
