Using 0 for A, 1 for B, and so on, let the numbers from 0 to 25 stand for the letters of the alphabet. In this way, convert a message to a sequence of strings of numbers. For example SEA becomes 18 4 0. What does (the numerical representation of) this word become if we shift every letter two places to the right? What if we shift every letter 13 places to the right? How can you use the idea of m mod n to implement a Caeser cipher?
