6a2037a68a0bc2aef0006002	Challenge 340: Pig Latin Converter	29	challenge-340

--description--

Given a string, convert it to Pig Latin using the following rules:

• If a word begins with a vowel ("a", "e", "i", "o", or "u"), add "way" to the end. For example, "universe" converts to "universeway".
• If a word begins with one or more consonants, move them to the end and add "ay". For example, "hello" converts to "ellohay".
• Preserve the case of the first letter. For example, "Hello" converts to "Ellohay".

--hints--

pig_latin("universe") should return "universeway".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(pig_latin("universe"), "universeway")`)
}})

pig_latin("hello") should return "ellohay".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(pig_latin("hello"), "ellohay")`)
}})

pig_latin("hello universe") should return "ellohay universeway".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(pig_latin("hello universe"), "ellohay universeway")`)
}})

pig_latin("Hello universe") should return "Ellohay universeway".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(pig_latin("Hello universe"), "Ellohay universeway")`)
}})

pig_latin("Pig Latin is fun") should return "Igpay Atinlay isway unfay".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(pig_latin("Pig Latin is fun"), "Igpay Atinlay isway unfay")`)
}})

pig_latin("The quick brown fox jumped over the lazy dog") should return "Ethay uickqay ownbray oxfay umpedjay overway ethay azylay ogday".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(pig_latin("The quick brown fox jumped over the lazy dog"), "Ethay uickqay ownbray oxfay umpedjay overway ethay azylay ogday")`)
}})
