Pluralize

Your Task 📚:

Create a function called pluralize that passes a list of words in the singular form, return a set of those words in the plural form if they appear more than once in the list. Note: just add 's' to the end of the word

Examples 😃:

pluralize(["cat","dog","cat","mouse"]) ➞ ["cats","dog","mouse"]
pluralize(["car", "car", "car"]) ➞ ["cars"]

Good Luck 😀
