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. WebA treeis a directed acyclic graph in which each node is the target of exactly one edge, except for one node (the root node) which is not the target of any edges 1.

WebA graph is like a tree data structure is a collection of objects or entities known as nodes that are connected to each other through a set of edges. A tree follows some rule that determines the relationship between the nodes, whereas graph does not follow any rule that defines the relationship among the nodes.

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. WebTree (data structure) This unsorted tree has non-unique values and is non-binary, because the number of children varies from one (e.g. node 9) to three (node 7). The root node, at the top, has no parent. In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes ...
