LeetCode 1557M 可以到达所有点的最少点数目Minimum Number of Vertices to Reach All Nodes 读题 解法一:入度为0的节点 简单来说,我们要找的是图中所有入度为0的节点,因为只有这些节点不是任何其他节点的目的地,所以从这些节点出发,可以到达图中的任何其他节点。
Even number of odd verticesTheorem: v∈Vdeg(v) = 2|E| for every graph G = (V,E).Proof: Theorem: Every graph has an even number of vertices with odd degree.Proof: 1
令V(n,p)表示随机图G(n,p)中孤立点的个数,其中p=c/n,c>0。 Let V(n, p) denote the number of isolated vertices in G(n, p), where p=c/n, c > 0 .
2. Show that a graph has an even number of vertices of odd degree. 相关知识点: 试题来源: 解析 If we add all the degrees of all the vertices, then we must obtain twice the number of edges,since each edge joins two vertices. Hence the sum of all degrees of all vertices is even. ...
