Given a string of words, write a function to reverse the words in the string. The function should also remove any leading or trailing whitespace and reduce multiple spaces between words to a single space.

Example:

Input: "This is the best"
Output: "best the is This"

Input: " space here"
Output: "here space"

Constraints:

• The input string may contain extra spaces, but the result should have no leading, trailing, or multiple spaces between words.
• The function should reverse the words, not the characters.
