WebDef 2.1. A directed tree is a directed graph whose underlying graph is a tree. Def 2.2. A rooted tree is a tree with a designated vertex called the root. Each edge is implicitly directed away from the root. r r Figure 2.1: Two common ways of drawing a rooted tree. 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 … raymond sd weatherWeb4. 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.
