Problem 2: • Is the graph G below Eulerian? If "Yes", find an Eulerian Circuit staring at v₁- (mark the first edge as 1, second one as 2, etc -check the notes); if "No", please explain why. Is the graph G Hamiltonian? If "Yes", find a Hamiltonian cycle. If "No", explain why. • Adding a new vertex v to G and joining v to every odd vertex of G. Determine whether this new graph is Eulerian or Hamiltonian or both or neither, and explain why.
