I could write out a detailed explanation of the differences between breadth and depth first traversals, but I'd probably get it wrong (I'm not a heavy comp-sci guy yet). Webhandle in a different way. 6.1 Basic definitions We begin with a flurry of definitions. Definition 6.1.A graph G(V,E) is acyclic if it doesn’t include any cycles. Another way to say a graph is acyclic is to say that it contains no subgraphs isomorphic to one of the cycle graphs. Definition 6.2.A tree is a connected, acyclic graph.

A ... Web4. So, a vertex is called a leaf if it connected to only one edge. a) Show that a tree with at least one edge has at least 2 leaves. b) Assume that G = (V, E) is a graph, V ≠ Ø, where every vertex has at least 2 edges, Show that G has a cycle. I don't really know for sure how to write the proofs for these two tasks, but here is what I have. how many pounds of hay does a sheep eat a day
