[LeetCode] Is Graph Bipartite? 是二分图么? Given an undirected graph, return true if and only if it is bipartite. bipartite graph formulation naturally leads to partial SVD problems for the underlying edge weight matrix which ad-mit efficient global optimal solutions. 这道题博主在最开始做的时候,看了半天,愣是没弄懂输出数据的意思,博主开始以为给的是边,后来发现跟图对应不上,就懵逼了,后来是通过研究论坛上大神们的解法,才总算搞懂了题目的意思,原来输入数组中的 graph[i],表示顶点i所有相邻的顶点,比如对于例子1来说,顶点0和顶点1,3相连,顶点1和顶点0,2相连,顶点2和结点1,3相连,顶点3和顶点0,2相连。这道题让我们验证给定的图是否是二分图,所谓二分图,就是可以将图中的所有顶点分成两个不相交的集合,使得同一个集合的顶点不相连。为了验证是否有这样的两个不相交的集合存在,我们采用一种很机智的染色法,大体上的思路是要将相连的两个顶点染成不同的颜色,一旦在染的过程中发现有两连的两个顶点已经被染成相同的颜色,说明不是二分图。这里我们使用两种颜色,分别用1和 -1 来表示,初始时每个顶点用0表示未染色,然后遍历每一个顶点,如果该顶点未被访问过,则调用递归函数,如果返回 false,那么说明不是二分图,则直接返回 false。如果循环退出后没有返回 false,则返回 true。在递归函数中,如果当前顶点已经染色,如果该顶点的颜色和将要染的颜色相同,则返回 true,否则返回 false。如果没被染色,则将当前顶点染色,然后再遍历与该顶点相连的所有的顶点,调用递归函数,如果返回 false 了,则当前递归函数的返回 false,循环结束返回 true,参见代码如下:, 我们再来看一种迭代的解法,整体思路还是一样的,还是遍历整个顶点,如果未被染色,则先染色为1,然后使用 BFS 进行遍历,将当前顶点放入队列 queue 中,然后 while 循环 queue 不为空,取出队首元素,遍历其所有相邻的顶点,如果相邻顶点未被染色,则染成和当前顶点相反的颜色,然后把相邻顶点加入 queue 中,否则如果当前顶点和相邻顶点颜色相同,直接返回 false,循环退出后返回 true,参见代码如下:, 其实这道题还可以使用并查集 Union Find 来做,所谓的并查集,简单来说,就是归类,将同一集合的元素放在一起。我们开始遍历所有结点,若当前结点没有邻接结点,直接跳过。否则就要开始进行处理了,并查集方法的核心就两步,合并跟查询。我们首先进行查询操作,对当前结点和其第一个邻接结点分别调用 find 函数,如果其返回值相同,则意味着其属于同一个集合了,这是不合题意的,直接返回 false。否则我们继续遍历其他的邻接结点,对于每一个新的邻接结点,我们都调用 find 函数,还是判断若返回值跟原结点的相同,return false。否则就要进行合并操作了,根据敌人的敌人就是朋友的原则,所有的邻接结点之间应该属于同一个组,因为就两个组,我所有不爽的人都不能跟我在一个组,那么他们所有人只能都在另一个组,所以需要将他们都合并起来,合并的时候不管是用 root[parent] = y 还是 root[g[i][j]] = y 都是可以,因为不管直接跟某个结点合并,或者跟其祖宗合并,最终经过 find 函数追踪溯源都会返回相同的值,参见代码如下:, https://leetcode.com/problems/is-graph-bipartite/, https://leetcode.com/problems/is-graph-bipartite/discuss/115487/Java-Clean-DFS-solution-with-Explanation, https://leetcode.com/problems/is-graph-bipartite/discuss/115723/C++-short-iterative-solution-with-comments.
