Return the number of complete connected components of the graph. A connected component is a subgraph of a graph in which there exists a path between any two vertices, and no vertex of the subgraph shares an edge with a vertex outside of the subgraph.

Apr 18, 2024 · Key Characteristics of Graphs and Trees: Graphs can be directed or undirected, contain cycles or be acyclic. Trees are a special case of graphs that are connected and acyclic. In graphs, each element is called a vertex, and the connections between vertices are called edges. DFS (Depth-First Search):
Mar 13, 2022 · Given an undirected graph G, with V vertices and E edges, the task is to check whether the graph is 2-edge connected or not. A graph is said to be 2-edge connected if, on removing any edge of the graph, it still remains connected, i.e. it contains no Bridges. Examples: Input: V = 7, E = 9 Output: Yes Explanation: Given any vertex in the graph, we c
Oct 18, 2016 · Number of Connected Components in an Undirected Graph. Description. You have a graph of n nodes. You are given an integer n and an array edges where edges[i] = [a i, b i] indicates that there is an edge between a i and b i in the graph. Return the number of connected components in the graph. Example 1: Input: n = 5, edges = [[0,1],[1,2],[3,4]]
Tarjan's Algorithm is popular algorithm for finding the Strongly Connected Components (SCC) of a directed graph. In the below graph, the nodes in a blue envelope constitute a single connected component as any node u u u as a path to another node v v v and vice versa.
