There is an undirected graph with n nodes, where each node is numbered between 0 and n - 1. You are given a 2D array graph, where graph[u] is an array of nodes that node u is adjacent to. More formally, for each v in graph[u], there is an undirected edge between node u and node v. The graph has the following properties:

\n\n\n\n

A graph is bipartite if the nodes can be partitioned into two independent sets A and B such that every edge in the graph connects a node in set A and a node in set B.

\n\n

Return true if and only if it is bipartite.

Example 1:

\n\"\"\n
\nInput: graph = [[1,2,3],[0,2],[0,1,3],[0,2]]\nOutput: false\nExplanation: There is no way to partition the nodes into two independent sets such that every edge connects a node in one and a node in the other.
\n\n

Example 2:

\n\"\"\n
\nInput: graph = [[1,3],[0,2],[1,3],[0,2]]\nOutput: true\nExplanation: We can partition the nodes into two sets: {0, 2} and {1, 3}.
