Solution: Graph Valid Tree

Explore how to determine whether a graph is a valid tree by implementing an algorithm that checks for cycles and full connectivity. This lesson guides you through building adjacency lists, performing depth-first search, and verifying conditions to confirm tree validity, enhancing your graph algorithm skills.

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 ...
