1) Create a user-defined function for an atbash cipher decrypter: def decrypt_atbash(text: str) ->str: "" " Decipher a text (Atbash cipher). """ \# TODO: Implement this function Pass For example: - Letter A is the first letter in the alphabet, so it will be replaced with the last letter, which is Z. - Letter D is the 4th letter in the alphabet, so it will be replaced with the 4th letter from the end, which is W. The program should correctly decrypt both upper-case and lower-case letters and keep all other characters (whitespace, punctuation, etc.) intact
