Problem 3 (a) Write a function that takes as input a string of characters, and returns the characters in reverse order (either as a list of characters, or as a string). Try your function on "MADWARWOLF". It should return "FLOWRAWDAM" (or a list of these characters). (b) Write a function that takes as input a string of characters, and applies the above reverse cipher, followed by a shift (Caesar) cipher like the one we did in class (shifting by an amount of your choice). How hard would it be to break this combination cipher?
