Number of Connected Components in an Undirected Graph

Explore how to determine the number of connected components in an undirected graph by analyzing edges and nodes. Learn to implement an efficient solution using union-find or graph traversal methods in JavaScript, optimize for O(E + V) time and O(V) space, and enhance your graph problem-solving skills.

We'll cover the following...

Statement

For a given integer, n, and an array, edges, return the number of connected components in a graph containing n nodes. ...
