Reverse the Words

You are given a string that may contain multiple spaces between words. Your task is to reverse the order of the words in the input string and output the resulting string with a single space separating the words. Note that any extra spaces at the beginning or end of the input should be ignored.

For example, given the input: Hello there how are you, the output should be you are how there Hello.

The mathematical description of the transformation is as follows:

$$\text{output} = \text{join}(\text{reverse}(\text{split}(\text{input},\ \text{whitespace})),\ ' ') $$

This means that you first split the input string into words by whitespace, reverse the resulting list, and then join the list back into a single string with a single space between each word.
