THE GREATEST GUIDE TO CIRCUIT WALK

In Eulerian route, every time we check out a vertex v, we walk by two unvisited edges with a person end point as v. As a result, all middle vertices in Eulerian Route needs to have even diploma. For Eulerian Cycle, any vertex can be Center vertex, hence all vertices need to have even diploma.$begingroup$ I feel I disagree with Kelvin Soh a bit, in
