Question 2: Encoding Cryptography is the study of trying to create secure information by obscuring the original message. One simple encryption method is to substitute letters f decrypt the hidden message, we may also remove clues such as the length of the words in the message and any punctuation or capitalization. Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: • Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included • The encrypted message will only contain uppercase letters. • Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet. In other words, A or a will become Z, B or b will become Y. c orc will become X. .. z or z will become A. • The encrypted message will have a single space separating each letter. You may assume that the letters in message are English letters only. For example: 1 > (encpde "Cat") 2 "X Z G" > (encode "A") 4 "" 5 > (encode "Is this correct?") 6 "R HGSRHXLIIV X G" Additional Restrictions

Question 2: Encoding Cryptography is the study of trying to create secure information by obscuring the original message. One simple encryption method is to substitute letters from the original message with other letters. To make it harder to decrypt the hidden message, we may also remove clues such as the length of the words in the message and any punctuation or capitalization. Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: * Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. * The encrypted message will only contain uppercase letters. * Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet. In other words, A or a will become Z, B or b will become Y, C or c will become X, ..., Z or z will become A. * The encrypted message will have a single space separating each letter. You may assume that the letters in message are English letters only. For example: 1 2 3 4 5 6 > (encode "Cat") "X Z G" > (encode "A") "Z" > (encode "Is this correct?") "R H G S R H X L I I V X G" > (encode "Cat") "X Z G" > (encode "A") "Z" > (encode "Is this correct?") "R H G S R H X L I I V X G"
