零基础学算法100天第1天——Dijkstra（图解最短路算法）（下）

5.Dijkstra核心代码实现为了方便大家理解和记忆，我将代码按照上面的逻辑分成几个板块方便大家记忆。1.初始化操作 //所有距离初始化为正无穷 Arrays.fill(dist,0x3f3f3f3f); //起点初始化为0，主要看起点的编号是几，这里默认为1 dist[1]=0...

零基础学算法100天第1天——Dijkstra（图解最短路算法）（上）

1.什么是最短路径问题？既然知道Dijkstra是用来解决最短路径问题，那我们肯定要先清楚是最短路径问题。最短路径通俗的来说，就是在一个图中，从一个起始源点，到另外一个点的最小代价。为什么是最小代码而不是最短路径？因为可能题意说的并不是距离，也有可能是需要花费的金钱或者时间等，但其实都是最短路径问题的模型。 ....
