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 working on C# language
the test give me this error:
"System.ArgumentOutOfRangeException : Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"
I copy and paste the expected output in the return sentence => "(6,12)(4,12)(3,12)" and it gave me the same error.
When I put a shorter or larger string it say me that the outputs doesn't match. But when I put the exact characters it give me the out of range error. What am I doing wrong?
