WebMar 29, 2024 · A graph is a data structure that consists of the following two components: 1. A finite set of vertices also called as nodes. 2. A finite set of ordered pair of the form (u, v) called as edge. The pair is ordered because (u, v) is not the same as (v, u) in case of a directed graph (di-graph). WebMar 24, 2024 · A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with graph vertices is denoted and has (the triangular numbers) undirected edges, where is …
WebA tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.

WebShow that a connected graph on n vertices is a tree if and only if it has n − 1 edges. ( ⇒) If a tree G has only 1 vertex, it has 0 edges. Now, assume that any tree with k − 1 vertices has k − 2 edges. Let T be a tree with k vertices. Remove a leaf l to obtain a tree T ′ with k − 1 vertices. Then, T ′ has k − 2 edges, by the inductive hypothesis. how many cups in a gillWebJun 4, 2024 · A graph is a tree if and only if the graph has no cycles.
