dataStructure@ Check whether a given graph is Bipartite or not

Check whether a given graph is Bipartite or not A Bipartite Graph is a graph whose vertices can be divided into two independent sets, U and V such that every edge (u, v) either connects a vertex from U to V or a vertex from V to U. In other words, fo…

Geeks - Check whether a given graph is Bipartite or not 二分图检查

检查一个图是否是二分图的算法使用的是宽度搜索: 1 初始化一个颜色记录数组 2 利用queue宽度遍历图 3 从随意源点出发.染色0. 或1 4 遍历这点的邻接点.假设没有染色就染色与这个源点相反的颜色,假设已经染色而且和源点的值相反.那么就是合法点,假设是同样的颜色.那么就不能是二分图參考:http://www.geeksforgeeks.org/bipartite-graph/ #include <stdio.h> #include <iostream> #include…

LeetCode 785. Is Graph Bipartite?

原题链接在这里:https://leetcode.com/problems/is-graph-bipartite/ 题目: 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 eve…
