I'm using Ruby, and I can't get any loops to work on any of these katas. The last five I've tried, I keep getting an error unexpected end, but I'm wording the loop correctly. I can't test anything, and I can't get anything passing.

I wrote a solution that works for the first 10 tests. It fails on the 11 tests, but doesn't give any information why, just says that I'm returning "NO" when I should return "YES". Hard to fix the code with no spec.

As with many people on here, my code is returning the correct answer according to the spec, but the expected answer in the tests is the unmodified string.

Mine too, any solution to this?
