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.…

类似于二叉树的三种遍历,我们能够基于遍历的模板做非常多额外的事情,图的两种遍历,深度和广度模板相同也能够做非常多额外的事情,这里举例利用深度优先遍历的模板来进行复制,深度优先中,我们先訪问第一个结点,接着訪问第一个邻接点,再訪问邻节点的邻节点.... class Solution: # @param node, a undirected graph node # @return a undirected graph node def cloneGraph(self, node): if None…
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.…
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…
