added to Ruby

Wow, I'm very impressed that this literally passes everything except the one case you mentioned. I'll see if I'm still allowed to edit this kata to add in that test case. Thanks a lot for the feedback!

I would like to see a solution that could pass all of the other tests, but not this one. Even if you did figure one out, the random tests should catch any invalid solutions anyway. I'm interested in seeing the solution though, and if it is a big enough issue, then I will change things.

There's at least one solution that passes all existing tests but would fail this valid test, please consider adding the following test:

Test.assert_equals(validate_word("abccabcd"), false)

GiacomoSorbi and MMMAAANNN have Edited the description and Added test cases Mark the issue resolved if satified, Happy Coding ^_^

Use more descriptive parameter names in the beginning code template. list_ and n could be more descriptive and the underscore suffix is unconventional for Ruby. Suggestion: words and sort_char_position as clearer param names. Good for participants to see good naming practices in the provided code.

My first solution didn't work for negative numbers, but instead of getting a nice error I got that true does not equal false. It should tell me what went wrong, like "isOdd(5) was expected to return true, but instead your implementation returned false."

Clarify description of handling negative floats

Thank you for the feedback. The test cases were actually already checking for the case of nil. I've added false to the list of possible values to check. When you run the acceptance tests, you see what memoized values they are checking - nil and false should be there, you can verify yourself.

That's a cool idea, but I can't change the test cases once over 500 people have completed the kata. Sorry!
