Problem 1: 铺地毯 乍一看吓cry,地毯覆盖...好像是2-dims 线段树,刚开头就这么难,再一看,只要求求出一个点,果断水题,模拟即可.(注意从标号大的往小的枚举,只要有一块地毯符合要求就输出,返回.) (全篇未完结,代码就不发了.) Problem 2: 选择客栈 模拟果断会超时,所以用类似动态规划的方法. 用$\text{sum}\left[ i\right]$表示从一号客栈到i号客栈途中的符合要求的Café总数,自然,$\text{O}\left( n\right)$的时间复…

题目 现在一圈n个花坛, 每次随机往一个花盆里种花, 一个花盆可以种多颗花, 假如一个花盆两边的花盆都有花, 那么他也将被种上花 问期望种满所有花盆要种几次 首先定义f(i)为放置了i个物品后完全覆盖的概率, 可以发现 \[f[i] = \frac{C_i^{n-i}}{C_{n - 1}^{i - 1}}\] 那么答案就是\[\sum_{i=0}^{n - 1}(1 - f[i]) \frac{n}{n - i}\] On了 #include<cstdio> #include<algo…
