    Agreed. 6 kyu is probably more accurate.

    So this solution shouldn't have passed. Some additional tests should be added that include uppercase vowels.

    Hard to tell if you did anything wrong if there is no code to view :(

    Nice kata. Added ruby translation.

    Agree. It's like a 6.5 kyu imo.

    I have the same issue in Ruby. I'm assuming that you (AlexIsHappy) give a very large 'r' in one of the tests, but the way codewars is setup the code just times out after ~6 seconds. Are you trying to get us to come up with a way to process very large numbers in a short period of time, or does the test need to be rewritten?

    needs some test cases

    One of the tests keeps failing (the last one in the section titled "Should return false for non-prime numbers"). Every other test passes.. what am I missing? Can anyone share a hint as to what I might be missing here?

    My solution keeps getting stuck on the 4th test saying that the '<' method doesn't exist for nil:NilClass. I'm not sure why this is happening as I'm removing all non-Fixnum's and Floats from the array before iterating through the array. What am I missing here?
