Problem

A MITRE ATT&CK content utility needs to display the words in a procedure description in reverse order. Given a string text, return a string containing the same words in reverse order, separated by exactly one space.

Input: text, a Python string.
Output: A Python string with words in reverse order and normalized spaces.

Constraints
