## pig_latin

### Instructions

Write a function that transforms a string passed as argument in its `Pig Latin` version.

The rules used by Pig Latin are the following:

- If a word begins with a vowel, just add "ay" to the end.
- If it begins with a consonant, then we take all consonants before the first vowel and we put them on the end of the word and add "ay" at the end.
- If a word starts with a consonant followed by "qu", move it to the end of the word, and then add an "ay" sound to the end of the word (e.g. "square" -> "aresquay").
