Find the Longest Word

Write a function that will return the longest word in a sentence. In cases where more than one word is found, return the first one.

Examples

find_longest("A thing of beauty is a joy forever.") ➞ "forever"

find_longest("Forgetfulness is by all means powerless!") ➞ "forgetfulness"

find_longest("\"Strengths\" is the longest and most commonly used word that contains only a single vowel.") ➞ "strengths"

Notes

• Special characters and symbols don't count as part of the word.
• Return the longest word found in lowercase letters.
