Decrypting messages

Difficulty:

Now that we know how to encrypt messages, let’s crack them!

Create a program that tries all possible ciphers (remember: a cipher is a value between 1 and 26) and prints them out. You should be able to select the right message from the list of all possible messages.

Try to decrypt the following messages: 1) ykefqdk 2) npmepykkgle 3) qbxzeboxobxkklvfkd 4) hkkozrrsghrbntqrd 5) qdzkkxknmfrdmsdmbdrvhsgzatmbgnevnqcr
