luogu AC通道! (官方数据) 题目描述 小智家里来了很多的朋友,总共有N个人,站成一排,分别编号为0到N-1,小智要给他们分糖果.但 是有的朋友有一些特殊的要求,有的人要求他左右的两个人(左边一个.右边一个,一共2个人)的 糖果数都比他的多,有的人要求他左右的两个人的糖果数都比他的少.同时小智希望给不同的人分到 的糖果数不相同,并且每个人至少有一个糖果,同时小智希望分出的糖果个数尽可能的少,现在小智 想知道有多少种分糖果的方法.数据保证不会出现两个人的要求产生冲突的情况. 输入格式 第一…

今天来尝试了几道数学期望相关的题,这是我认为比较有趣的一道题 这次不废话啦直接开始~ 一句话题意:两个分别装有n个糖果的盒子,每次随机选一个盒子然后拿走一颗糖(选的概率分别是\(p\)和\((1-p)\)),直到有一次选了一个盒子打开之后发现没有糖果了,求另一个盒子糖果个数的期望值 \(n<=2*10^5\) 嗯首先我们得知道期望的线性性质:\(E(X+Y)=E(X)+E(Y)\) 如果我们假设最后打开的是第一个盒子,那么第二个盒子的糖果个数其实可能有\(0~n\)个,如果已经知道了有\(i\)…
