Solution: Graph Valid Tree

Explore how to determine if a graph is a valid tree by applying depth-first search and adjacency list representations. Learn to check edge count for cycles, perform graph traversals, and confirm connectivity. This lesson enables you to implement an efficient solution for verifying tree structures in graphs with clear time and space complexity understanding.

We'll cover the following...

Statement

Given n as the number of nodes and an array of the edges of a graph, find out if the graph is a valid tree. The nodes of the graph are labeled from 00 to n−1n - 1, and edges[i]=[x,y]edges[i] = [x, y] represents an undirected edge connecting the nodes xx and yy ...
