Create an A1Z26 decrypter: def decrypt_a1z26(text: str) str: """ Decipher a text (A1Z26 cipher). """ \# TODO: Implement this function pass A1Z26 method is a substitution cipher. It means that it replaces the letter with its number in the alphabet. For example: - Letter A is the first letter in the alphabet, so it will be replaced with 1. - Letter D is the 4th letter in the alphabet, so it will be replaced with 4. - Thus, message AD will be replaced with 1-4 (a dash is added between each two numbers). - The program should correctly decrypt both upper-case and lower-case letters and keep all other characters (whitespace, punctuation, etc.) intact. Must be able to decrypt without converting the string to upper/lower case. - You can assume that the original message will not contain any numbers - The A1Z26 cipher is case-insensitive, so you will lose the information about the case of the letters. It's fine
