'''
Our fruit guy has a bag of fruit (represented as an array of strings)
where some fruits are rotten. He wants to replace all the rotten pieces
of fruit with fresh ones. For example, given ["apple","rottenBanana","apple"]
the replaced array should be ["apple","banana","apple"]. Your task is to
implement a method that accepts an array of strings containing fruits should
returns an array of strings where all the rotten fruits are replaced by good ones.

Notes

    If the array is null/nil/None or empty you should return empty array ([]).
    The rotten fruit name will be in this camelcase (rottenFruit).
    The returned array should be in lowercase.
