题目大意:给一个点阵,其中有的地方没有点,操作是去掉某个点,并询问当前点阵中最大的正方形 若没有修改的话,裸dp 加上修改,可以考虑时光倒流,这样答案就是递增的 可以用并查集维护点的连通性,O^2的 #include<bits/stdc++.h> using namespace std; #define maxn 2010 inline void MIN(int &a,int b){if(a>b)a=b;} inline void MAX(int &a,int b){if…

[PA2014]Parking 题目大意: 停车场是一个宽度为\(w(w\le10^9)\)的矩形.我们以其左下角顶点为原点,坐标轴平行于矩形的边,建立直角坐标系.停车场很长,我们可以认为它一直向右边伸展到无穷远处. 总共有\(n(n\le5\times10^4)\)辆车.车都是边平行于坐标轴的矩形,大小可能不同.你可以将车在停车场内任意地平移,且不能互相重叠. 告诉你每辆车目前的位置和目标位置,求是否可以通过移动达到目标状态. 思路: 如果两辆车路线必定会相交,且两辆车宽度加起来大于\(w\)…
