Web261. Graph Valid Tree. Given n nodes labeled from 0 to n-1 and a list of undirected edges (each edge is a pair of nodes), write a function to check whether these edges make up a valid tree. Example 1: Input: n = 5, and edges = [ [0,1], [0,2], [0,3], [1,4]] Output: true. Example 2: Input: n = 5, and edges = [ [0,1], [1,2], [2,3], [1,3], [1,4 ... WebA tree is an undirected graph in which any two vertices are connected by exactly one path.In other words, any connected graph without simple cycles is a tree. Given a tree of n nodes labelled from 0 to n - 1, and an array of n - 1 edges where edges[i] = [a i, b i] indicates that there is an undirected edge between the two nodes a i and b i in the tree, you can …
