Daniel and Ria are taking a road trip from Somerville to Vancouver (that’s in Canada). Because it’s a 52-hour drive, Daniel and Ria decide to switch off driving at each rest stop they visit; however, because Ria has a better sense of direction than Daniel, she should be driving both when they depart and when they arrive (to navigate the city streets). Given a route map represented as a weighted undirected graph G = (V, E, w) with positive edge weights, where vertices represent rest stops and edges represent routes between rest stops, devise an efficient algorithm to find a route (if possible) of minimum distance between Somerville and Vancouver such that Daniel and Ria alternate edges and Ria drives the first and last edge. Specify the space and time complexity.
