You are trying to send a secret message, and you've decided to encode it by replacing every letter in your message with its corresponding letter in a backwards version of the alphabet. What do your messages look like?
Create a program that replaces each letter in a message with its corresponding letter in a backwards version of the English alphabet.
A string of your message in its normal form.
A string of your message once you have encoded it (all lower case).
Hello World
svool dliow
If you replace each letter in 'Hello World' with the corresponding letter in a backwards version of the alphabet, you get 'svool dliow'.
