    Given historical traffic flow data for different segments of a delivery route, find the continuous sequence of route segments that yields the highest combined delivery efficiency score when their performance ratings are multiplied together. Each segment's score reflects traffic conditions and delivery success, where positive values indicate smooth operations and negative values represent delays or congestion.
