原创图论之邻接表的数组实现

虽然邻接矩阵真的很方便，很简单，很利于理解，但却有着一些重大缺陷；当我们遇到的是一张稀疏图的时候，邻接矩阵就造成严重的空间浪费，更直接一点，就是根本存不下来；这个时候就不得不考虑其他存图方式了，这个时候另一种流行的存图方式就登场了——邻接表，当然使用vector数组也是一种良好的选择；邻接表的实现可以通过链表或数组的方式实现，我这里主要讲数组的实现方法；首先，有三个数组，分别为u[

原创最短路之Dijkstra

Dijkstra算法适用于边权为正的情况，可用于计算正权图上的单源最短路径；其算法的思想在于，从单个源点出发，找到距离其最近的结点，然后松弛路径，反复重复上述操作，就可以得到固定源点到图上任意一个顶点的最短路径；这个算法的代码和prim算法的代码很像；void dijkstra(){ bool vis[105];//标记数组，记录结点是否被访问过； int d
