一.题意 求椭圆内接矩形周长的期望. 二.推导过程 已知$c$,容易得出矩形弦长$d=4a\sqrt{1-\frac{c^2}{b^2}}$ 接下来,矩形周长$p=4c+d=4c+4a\sqrt{1-\frac{c^2}{b^2}}$ 那么,椭圆内接矩形周长的期望值$E=\frac{\int_{0}^{b}(4c+4a\sqrt{1-\frac{c^2}{b^2}})\, dc}{b}$ 令$F(c)=\int_{0}^{b}(4c+4a\sqrt{1-\frac{c^2}{b^2}})\, d…

一.题意 给定一个元素个数为$N(1 \le N \le 10^5)$初始序列$a$和$b$,$a$序列的初始值全为$0$,$b$序列的初始值为$1$到$N$的一个排列.有$T(1 \le T \le 10^5)$次操作.操作有如下两种类型: 1.$add\ l\ r$:给序列$a$的区间$[l, r]$内所有元素加$1$: 2.$query\ l\ r$:查询$\sum\limits_{i=l}^{r}\lfloor{\frac{a_i}{b_i}}\rfloor$,并输出. 二.简要思路概括…
