a. Develop a Caesar cipher-type encryption algorithm with a little more complexity in it. For example, the algorithm could alternatively shift the cleartext letters positive and negative by the amount of the key value. Variations on this are limitless.
b. Select a single-digit key.
c. Code a short message using the algorithm and key.
d. Give your instructor the algorithm, key, cleartext, and ciphertext.
e.  Your instructor will randomly redistribute to the class the ciphertext messages completed in part c above. You are to decode
 message you receive as an additional assignment.
