CF1279F New Year and Handle Change 题解
来翻译一下 cf 评论区一老哥的证明。 首先问题可以转化为选出 $k$ 个长为 $l$ 的区间使得覆盖的 $1$ 个数最多。 不妨设 $kl\le n$,设选 $k$ 个区间最多能覆盖 $f_k$ 个 $1$,显然存在一种最优方案使得区间两两不交。 下面证明 $f_{k+1}\ge \frac{f_ ......

题面传送门 还是见识太少了。 直接算颜色个数不好算,因为是和式,所以考虑计算某个颜色的贡献。 对于某个时刻,有一些位置是当前时刻,那么设所有没有这些位置的联通块平方和为 $S$ ,则贡献为 $n^2-S$。 因为总共有效的修改只有 $O(m)$ 个,因此我们需要支持:改变一个点的状态,查询为 $1$ ......
