Given an undirected graph, return true if and only if it is bipartite. Example 1: Input: [[1,3], [0,2], [1,3], [0,2]] Output: true Explanation: The graph looks like this: 0----1 | | | | 3----2 We can divide the vertices into two groups: {0, 2} and {1…

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.…

785. 判断二分图 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], […
