    I had the same issue. Removing all System.out.println lines solved it for me. Thank you!

    I like this Kata, however, there is one point that was rather confusing. It is stated that the function/method has to return an array "of the first n elements - signature included" of the parameter array s. Plus, it is guaranteed that the signature always contains 3 values. So how come that there are tests that expect arrays of length less than 3 (e.g. 1) as a return? It would be nice, if some one could clarify that for me.
