# Pig Latin
# =========
#
# Implement a program that translates from English to Pig Latin.
#
# Pig Latin is a made-up children's language that's intended to be
# confusing. It obeys a few simple rules (below), but when it's spoken
# quickly it's really difficult for non-children (and non-native speakers)
# to understand.
#
# - **Rule 1**: If a word begins with a vowel sound, add an "ay" sound to
#   the end of the word.
# - **Rule 2**: If a word begins with a consonant sound, move it to the
#   end of the word, and then add an "ay" sound to the end of the word.
#
# There are a few more rules for edge cases, and there are regional
# variants too.
#
# Let the tests drive your implementation.
# Click run in the upper left to run the test suite.
