    I think in order to solve this Kata with only fundamental knowledge is possible but so time consuming it deserves to be a in more advanced kyo.
    The key is that all the test cases are all iterable objects and you need to iterate over them in order to remove the repeated caracters being them strings or arrays (including arrays of numbers, buy they are iterable anyways) NOT numbers, dont worry.
