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.
No problem, The sample tests in C# seem fine, and there is a fixed test for n = 10 in the final tests:
That also looks good.
And that's what you're asked to do:
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.
I just looked and I see that this kata has been solved 2416 times in C# - do you have a specific problem, with specific inputs/results that makes you think you have found a real error with the kata? Because 2416 other people seemed to solve it OK.
