// CSIS 2610L: Final Exam Lab
// DUE: Friday, May 1st 2026, 11:59pm

// ===== L1: Bizarro World (30 pts.) =====

// In Bizarro World, all the letters of the alphabet correspond with the 
// Latin symbols in reverse order.
// E.g., our 'a' = their 'z', our 'b' = their 'y', etc., and their 'z' = our 'a'.
// The same applies for uppercase letters, e.g., our 'A' = their 'Z', etc.
// Write a function that takes a string as input, and returns the Bizarro 
// World equivalent.  NASA scientists have figured out some of the code for you.
// Replace the TODO: comments with the code that ought to be there.
// Note that punctuation characters and symbols should be preserved, i.e., they are the same 
// in both worlds.  This should be remind you of the Caesar's Cypher problem.

// It may be helpful to revisit your code from Exam 2 for ideas!
// NOTE: the function you create will, by definition, also
// decrypt the bizarro message (it is invertible).

// Please submit your Lab Section solutions (in one file, named 
// username_final_L1.cpp, where username is your student email username 
// before the @ sign) via email to: james.dittrich+YSU@gmail.com
