题意:给你一个长度为奇数\(n\)的序列.你可以对任意元素加上\(k\)次\(1\),求操作后的中位数最大. 题解:先对序列进行排序,然后对中位数相加,如果中位数和后面的元素相等,就对后面所有和当前中位数相等的元素++,然后再对中位数++,不断往复这个过程就好了,具体看代码. 代码: int n; ll k; ll a[N]; ll cnt[N]; int main() { ios::sync_with_stdio(false);cin.tie(0);cout.tie(0); cin>>n&g…

题意 给出一个长度为n的有序序列.给出m个询问,每个询问包括四个正整数l1,r1,l2,r2你用l1tor1的和l2tor2的元素来组成一个新的序列,然后找出这个序列的中位数. 分析 这是当时Spring Team Training D 的一道题,显而易见的模拟,我当时在场上写了190行. 赛后看了学长的代码后···orzzzzz!! 我当时分类的时候是把 “相交不包含(l2<r1&&r2>r1)”,和“包含(r2<r1)”作为两种情况来写.然而事实上,如果是包含,只需要…

也是神奇的题目.. 原题传送门 首先看到这道题目,很明显我们需要线性算法 1.前缀和+统计 2.DP+统计 对于第一种算法,我们可以对于任何一个a[i]对b进行比较,如果大于b标上1,等于b标上0,小于b标上-1: 以0为中介,前缀和前后展开统计答案即可..学长的神奇做法,不讲.. 第二种算法啊,, 其实和第一种算法差不多 首先我们找到中位数b 对其左边和右边进行搜索 对于右边if(a[i]>a[i-1])f[i]=f[i-1]+1;else f[i]=f[i-1]-1; 左边同上,不过i-1改…
