2. You are tasked to establish a secret communication procedure for members of your team. You choose to encode the messages using the A1226 cypher, by which each alphabet letter is replaced by its number in the alphabet, i.e., A is 1, B is 2, C is 3, ... and Z is 26. a) First, produce the letter (A to Z) and number (1 to 26) character vectors. (2 marks) b) Using the above vectors, character substitution, and a control structure, encode the following message: "h-i-b-y-e" Note that for simplicity, the message must not contain any repeated letters as a rule. (3 marks) c) Wrap your code from 2(b) in a function that can receive and cypher any message. Test your code with a unique message. (5 marks) [TOTAL 10 MARKS]
