数据结构之图 图(Graph) 包含 一组顶点:通常用V (Vertex) 表示顶点集合 一组边:通常用E (Edge) 表示边的集合 边是顶点对:(v, w) ∈E ,其中v, w ∈ V 有向边<v, w> 表示从v指向w的边(单行线) 不考虑重边和自回路 无向图:边是无向边(v, w) 有向图:边是有向边<v, w> 连通:如果从V到W存在一条(无向)路径,则称V和W是连通的 连通图(Connected Graph):如果对于图的任一两个顶点v.w∈V,v和w都是连通的,则称…
题目描述: Farmer John has been informed of the location of a fugitive cow and wants to catch her immediately. He starts at a point N (0 ≤ N ≤ 100,000) on a number line and the cow is at a point K (0 ≤ K ≤ 100,000) on the same number line. Farmer John has…

一.基本思想 1)从图中的某个顶点V出发访问并记录: 2)依次访问V的所有邻接顶点: 3)分别从这些邻接点出发,依次访问它们的未被访问过的邻接点,直到图中所有已被访问过的顶点的邻接点都被访问到. 4)重复第3步,直到图中所有顶点都被访问完为止.   二.图的存储结构…
