It is about how to choose btw. BFS and DFS. My init thought was to DFS - TLE\MLE. And its editorial gives a very neat BFS based idea which costs much less memory. https://www.hackerrank.com/challenges/beautiful-path/editorial…

PropertyGrid是一个很强大的控件,使用该控件做属性设置面板的一个好处就是你只需要专注于代码而无需关注UI的呈现,PropertyGrid会默认根据变量类型选择合适的控件显示.但是这也带来了一个问题,就是控件的使用变得不是特别灵活,主要表现在你无法根据你的需求很好的选择控件,比如当你需要用Slider控件来设置int型变量时,PropertyGrid默认的模板选择器是不支持的.网上找了许多资料基本都是介绍WinForm的实现方式,主要用到了IWindowFromService这个接口,并…

题意: 给定一个有重边有自环的无向图,n个点(2 <= n <= 100000), m条边(1 <= m <= 200000), 每条边有一个权值, 求从第一个点到n的最少步数, 如果最少步数相同有多条路径, 那么输出权值字典序最小的一条. 分析: 用BFS解决最短路问题, 可以先从终点BFS, 求出每个点到终点的最短距离. 那么最少步数就是起点的最短距离, 最短路径就是从起点每次向最短距离比自己少1的顶点移动(如果有多个则可以随便走), 这样就可以保证走的是最短路径, 如果一开始…
