What is with the random tests?
I'm doing a C# exercise and I get the below failure
"98083 10002 5468 2833" fails in first interation because it expects 18956 but 10002 * 5468 * 2833 is 320599032

Most of the random tests fail because of overflow issues.
I've even seen a random test fail because the array of {38022, 72010} doesn't produce an expected of -40950
You have a basic testcase of {12,20} that expects a result of {20,12}
An array of {38022, 72010} should produce an expected result of {72010, 38022} based on your basic testcase
I get this failure instead:
Test Failed
Expected and actual are both <System.Int32[2]>
Values differ at index [0]
Expected: -40950
But was: 72010

I agree, the Add()() signature is something I've never seen and is very confusing, being able to research Function Currying would have helped

I selected this kata by mistake not realizing it isn't for the C# language.
How can I remove it from my unfinished kata?

The instructions state only "The input string can be assumed to contain only alphabets (both uppercase and lowercase) and numeric digits"
The random test is always a unicode input and always fails.
The instructions don't state you have to do any translation.
I can't complete this kata because of the random test
