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.

OP solved it, closing
I can't reproduce it.
The
ArgumentOutOfRangeExceptiongenerally occured in C# for solutions creating a negative range (one of the test cases is zero). The "Unknown error" seems to have been fixed since, now it will display the exception which should be a sufficient hint for debugging.I'm getting an ArguementOutOfRangeException which appears to be overflowing an int, which doesn't make any sense unless it was set up incorrectly.
I don't agree with what this kata requires, but you have to type check the array.

Is it still this? becuase this is correct, turning once more would put a 0 adjacent to 2 other 0's.
