You are given an integer n. There is an undirected graph with n vertices, numbered from 0 to n - 1. You are given a 2D integer array of edges where edges[i] = [ai, bi] denotes that there exists an undirected edge connecting vertices ai and bi.
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.
A connected component is said to be complete if there exists an edge between every pair of its vertices.
Hey @Nikhil-2002 I am interested in this issue. Please assign this to me. I can provide a very easy-to-understand solution to this problem. Please assign me.
