Thank you! There is definitely something wrong with the Ruby version.

Well I appreciate you trying to help, but I did not find your comment helpful. I have rewritten my solution 3 different ways (one of which does implement the reduce or inject method) and I am still getting the same results. EVERY SINGLE test is saying that my solution returned 0, when in fact it does not. I know this because I ran my solution on another code editor with the exact same arguments given on the real test and my solution does not return 0. I am not sure how to make this anymore clear, so I will copy and paste the info below. You will see that I pass basic tests just fine, then below that it shows that my solution returns 0 everytime.

Test Results:

This kata does not work correctly for Ruby. My solution works fine for sample test cases then fails on every random test. The biggest sign that it is faulty is that it says every single one of the return values for my soltion on the random test cases is 0... I ran the same code with the same arguments in my own editor and it worked just fine.

I am finding the exact same problem with Ruby. Here is what the log is saying:

Testing for KEh 0dWvbIKg and 7EhpFUsvbIKg
It should work for random inputs too - Expected: "7EhpFUsvbIKg\n", instead got: "KEh 0dWvbIKg\n7Eh 0dWvbIKg\n7Ehp0dWvbIKg\n7EhpFdWvbIKg\n7EhpFUWvbIKg\n7EhpFUsvbIKg\n"

My solution passes all normal tests bu fails ALL of the random tests because the random tests solution is just "#{s2}\n"...

In Ruby, the method name being tested for is hoop_count however the preloaded working method name is hoopCount. Had to manually change the working method name to hoop_count to avoid error.
