Hi,

Well... :/

• no invalid case in the sample tests
• no valid case in the full test suite
• no random tests in the full test suite
• the outputs aren't specified in the description
• the outputs aren't consistent: valid! but invalid without exclamation mark while the user has to run the full test suite to know that
• the output type doesn't make sense: the function should return a boolean, not strings (which is what the current description implies!)

unpublishing.

If you're interested in authoring kata, I strongly suggest that you read the whole documentation about it before your next attempt:
