"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 a tree is different from graph

Web$\begingroup$ My understanding of tree is that trees are not only a form of directed graph but the nodes are ORDERED, making the tree unique from a graph. Because a tree is ordered, there are no loops. Thus, a node shouldn't ever appear as multiple different nodes of the tree unless the implementer did something very wrong, because keeping track of … Web1 de jan. de 2024 · Tree: A tree is a special type of graph that is connected and acyclic, meaning that there are no cycles in the graph.
