HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD CIRCUIT WALK

In Eulerian route, each time we pay a visit to a vertex v, we walk by means of two unvisited edges with a person end position as v. Thus, all Center vertices in Eulerian Route must have even degree. For Eulerian Cycle, any vertex might be Center vertex, as a result all vertices will need to have even degree.A circuit needs to be a closed path, but
