# The Problem:
# From Wikipedia: "ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher 
# that replaces a letter with the letter 13 letters after it in the alphabet."

# Imagine a generic ROT-n on the ASCII lower-case alphabet.

# ROT-1 transforms "abbc" -> "bccd" and "zaab" -> "abbc".
# ROT-2 transforms "abbc" -> "cdde" and "zaab" -> "bccd".
# ...
# ROT-25 transforms "abbc" ->"zaab" etc.
