Web(a) If T has nleaves, show that it has n 2 vertices of degree 3. Let mbe the number of vertices of degree 3. So there are m+ nvertices in general, and thus m+ n 1 edges. The sum of the degrees of the vertices is twice the number of edges, so n+ 3m= 2((m+ n) 1). Rearranging, m= n 2. (b) Let Tbe a trivalent tree with n 4. WebJun 2, 2014 · If the sum of the degrees of vertices with odd degree is even, there must be an even number of those vertices. By the way this has nothing to do with "C++ graphs". It is a general property of graphs as per their mathematical definition Edit : This statement is only valid for undirected graphs, and is called the Handshaking lemma. Share

Of course, an … • An undirected graph has an Eulerian cycle if and only if every vertex has even degree, and all of its vertices with nonzero degree belong to a single connected component. • An undirected graph can be decomposed into edge-disjoint cycles if and only if all of its vertices have even degree. So, a graph has an Eulerian cycle if and only if it can be decomposed into edge-disjoint cycles and its nonzero-degree vertices belong to a single connected component. thylacine reproductionWebProof: Every edge hits two vertices, so the sum of the degrees of the vertices equals twice the number of edges. So it is even. The lemma follows immediately. Proof of the theorem Rather than giving the details of this proof, here is an alternative algorithm due to Hierholzer that also works. thylacine roads
