- Exercise 18. Write a function that implements a substitution cipher.
In a substitution cipher one letter is substituted for another to
garble the message. For example A -> Q, B -> T, C -> G etc. Your
function should take two parameters, the message you want to encrypt,
and a string that represents the mapping of the 26 letters in the
alphabet. Your function should return a string that is the encrypted
version of the message.
