Hey. I have some troubles submitting my solution to this problem. Since yesterday I keep having the message : "The server is not available. Wait a few minutes, and then retry your request. If the problem persists, contact the instructor." My solution when I tested it in the pad successufully passes through all the tests though. Any idea what the problem could be ?
