1 week ago Perhaps the same applies to case 4, but I didn't check. Code produces perfect outputs for everything else and works correctly on the previous tasks (10.2.2 & 10.2.3) so it is likely a mistake made when dealing with non-letter characters. Perhaps I should put this on the 10.1.1 page as well so we can get it clarified what to do with such characters there as well.
Case 3 Sample Output seems to have an odd vigenere cipher. It appears to be repeating "UPU" instead of just "UP", meaning that "Boiler" gets shifted by "UPUUPU" instead of "UPUPUP". While this could be a way to deal with the "!" in "Up!", I think it is a non-standard method which isn't laid out in 10.1.1.
