    Given a list of professional skill rankings where each number represents an individual's expertise level within a 50-mile radius, determine the total number of potential mentorship pairs by finding instances where a higher-ranked professional appears after a lower-ranked one in the list. Each such pair represents a viable mentorship opportunity where the more experienced professional can guide the less experienced one, and your task is to count all such possible mentor-mentee combinations.
