C. Maximum Median 题意: 给定一个数组,可每次可以选择一个数加1,共执行k次,问执行k次操作之后这个数组的中位数最大是多少? 题解:首先对n个数进行排序,我们只对大于中位数a[n/2]的数进行操作,所以这个最大中位数的取值范围是确定的,在区间[  [a[n/2],a[n-1]  ]之内,二分枚举最大的中位数x; 通过判断使x成为最大中位数的操作数是否大于k来缩小范围 #include<iostream> #include<string.h> #include<…

传送门 看到中位数考虑先把数排序一下 然后有个显然的贪心,一个数增加后一定不能比下一个数大,不然我们直接增加下一个数显然更优 所以初始时的中位数操作后也是中位数 那么我们只要考虑中间再往后怎么加使得答案最大 为了使中位数比较大当然先把中间位置加到和下一个位置一样大,然后为了继续增大又要把后面两个位置增大,然后是后面三个... 所以直接枚举和中间往后第几个即可 设最终答案为 $ans$ ,中间往后一共有 $x$ 个位置一起加,初始时的数列为 $a_i$ 那么 $ans*x=(\sum_{i=mid…
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:就是给一n(奇数)个元素数组,可以对它的元素执行k次+1操作,递增排序,求中位数最大是多少. 那我们在排完序之后,中位数前的元素可以不管它,只要对中位数后的操作就行,我们要判断和中位数相等的元素有几个,再用k减去它,循环一下,当k小于0时没的减了,也就是数组元素不能再加了时跳出来. 附ac代码: 1 #include<cstdio> 2 #include<iostream> 3 #include<cstring> 4 #include<cmath> 5…
