Problem In this problem, a tree is an undirected graph that is connected and has no cycles. The given input is a graph that started as a tree with N nodes (with distinct values 1, 2, ..., N), with one...
题目 For an undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called ...

Problem 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 Given n = 5 and...
Problem Given an undirected graph, return true if and only if it is bipartite. Recall that a graph is bipartite if we can split its set of nodes into two independent subsets A and B such that every ed...
