This kata is broken for C#. Same input is used in two different test cases at least and gives me two different results ensuring it's impossible for me to actually complete this kata. I've even tried randomizing the output between 0 and -1 to try to get around it but that hasn't worked yet, but the array [1,2,3,4,5,6] wants both a 0 and -1 answer, which is ridiculous. I pass all the randomized test cases with flying colors.

I've got to rank 5 kyu when I was around 310 honor, and that was doing mostly 8 kyu problems with a sprinkling of higher level problems.
