1.  A software solution displays a map of the Long Island highway system used to display traffic travel times on a web page. The map displays principle towns, intersections, and major landmarks, the roads that connect them, and the travel times between them along those roads. Travel times along the same road may be different in different directions. What is the best data structure to achieve this solution? 2. In the previous question, vertices would connect what entities? Principle towns and intersections Principle towns, intersections, and major landmarks Major landmarks only Principle towns only
