Show that there is no four-vertex undirected graph with degrees (dleft(v_{1} ight)=3, dleft(v_{2} ight)=2, dleft(v_{3} ight)=2), and

Show that there is no four-vertex undirected graph with degrees \(d\left(v_{1}\right)=3, d\left(v_{2}\right)=2, d\left(v_{3}\right)=2\), and \(d\left(v_{4}\right)=2\).
