Lmao. No way this is 7 kyu

No problem, The sample tests in C# seem fine, and there is a fixed test for n = 10 in the final tests:

Assert.AreEqual("Great, now move on to tricks", Kata.HoopCount(10), "Should work for 10");

That also looks good.

Yes, It passes the test if n = 10. What I want to say is test sample does not seem do be correct. Sorry if I talk big. I just starded to learn coding.

And that's what you're asked to do:

If Alex gets 10 or more hoops, return the string "Great, now move on to tricks".

This code returns "Great, now move on to tricks" if n = 10
So this is not the best practice. We should instead ask if n >= 10.

I used Convert class in C#, however this class is not included in this kata. I tested the code on .NET. It works fine. But how can I convert string to char without using Convert class?

Oh, thank you! Did not notice that. Just fixed it.

Your code returnrs true for a = 100, b = 1 and c = 1.

Did you read all the way to the end of the kata description? See this part:

Input validation

If an empty value ( null, None, Nothing etc. ) is given instead of an array, or the given array is an empty list or a list with only 1 element, return 0.

my code passed 6 tests but failed 3. It can not pass when the given array is null or has only one value.
