    Hi.

    Why the instructions says you can use the scale twice but a commentary in code says that you can use max 4 times?

    Thanks for your answer.

    The following test make my thought that solution must be non case-sensitive:
    Test.assertEquals(hasUniqueChars(" nAa"),false)
    But the tests when I submit my solution take care about that so check please.
