WHAT DOES CIRCUIT WALK MEAN?

In Eulerian route, each time we pay a visit to a vertex v, we walk by means of two unvisited edges with a single stop level as v. Consequently, all middle vertices in Eulerian Route needs to have even degree. For Eulerian Cycle, any vertex can be Center vertex, thus all vertices must have even diploma.Might to late October (Wintertime time): Walkin
