在进行DFS的时候,进行逐步深入的搜索。注意的是这里使用的是stack. 如果起点是A的话,经过的路径是一个逐渐深入的过程 A -> C -> E -> D ->F ->B。 #include<iostream>#include#include<vector>#include<algorithm>#include<stack>#include<set>template<typenameT>usinggraph_type=std::map<T,std::vecto...

在计算机中,图的存储方式有很多种,最常用的是邻接矩阵和邻接表。邻接矩阵的适用范围一般很小,我们不考虑这种写法。 本文将讨论对于图的邻接表的建立(通过vector),以及BFS、DFS对图进行遍历。 课程大纲:eriktse.com/algorithm/1 作者:Eriktse 简介:211计算机在读,CCPC全国赛金牌,ICPC区域赛银牌退役选手 力争以通俗...
