Given a set of N people (numbered 1, 2, ..., N), we would like to split everyone into two groups of any size. Each person may dislike some other people, and they should not go into the same group. Formally, if dislikes[i] = [a, b], it means it is not…

Given an undirected graph, return true if and only if it is bipartite. Recall that a graph is bipartite if we can split it's set of nodes into two independent subsets A and B such that every edge in the graph has one node in A and another node in B.…

1. 具体题目 给定一个无向图graph,当这个图为二分图时返回true.如果我们能将一个图的节点集合分割成两个独立的子集A和B,并使图中的每一条边的两个节点一个来自A集合,一个来自B集合,我们就将这个图称为二分图.graph将会以邻接表方式给出,graph[i]表示图中与节点i相连的所有节点.每个节点都是一个在0到graph.length-1之间的整数.这图中没有自环和平行边: graph[i] 中不存在i,并且graph[i]中没有重复的值. 示例 1: 输入: [[1,3], [0,2],…
