分层图最短路。。。听起来有点高大上，其实就只是相当于三维的最短路而已，和三维迷宫一样，我们用dis[i][k]表示起点S到第k层i的最短路，其中同层的图如果是无向图，继续保持，然后用一条由该层指向上一层的有向线段并且费用为0，作为该层到上一层的道路，实际上就是这样的： 由该层向上一层改点的相邻点建边，建完之后就可以直接开始跑最短路了，当然，有2种跑法，（一）可以将k层的点全部列出来，也就是总共k*n个点，然后建很多的边，最后跑最短路，结果访答案的时候： for (int i=0; i<=k; i++) ans=min(ans,dis[t+i*n]); （二）普通建边，在跑最短路的队列里面进行操作，这个就比较方便，下面给出代码： void dij(int st,int ed,int k,int n) { priority_queue<node>q; q.push(node{st,0,0}); dis[st][0]=0; while (!q.empty()){ node now=q.top(); q.pop(); int id=now.id%n,fl=now.floor; if (vis[id][fl]) continue; vis[id][fl]=1; for (int i=head[id]; i!=-1; i=eg[i].next){//同层最短路 int v=eg[i].to;

And found a lot of different styles of the flexbox statements. Some guys write display: box; , some use display: flexbox; and other display: flex; . So what are the differents? Which i should use? 回答1: These are different styles. display: box; is a version of 2009. display: flexbox; is a version of 2011. display: flex; is the actual version.

I've been able to get it to work by calling it on one of my buttons which is always present in the view, but this feels wrong - and I'm sure there must be a way to get around this. I tried referencing the current focus like this: getCurrentFocus().setKeepScreenOn(true); but that threw a NullPointerException. Maybe there was no current focus. So, can anyone tell me how I can
