@tuoran 空格

@tuoran 哥，你空格呢？？

by Scez @ 2024-08-21 19:23:28

@tuoran 哥你怎么输入了两遍

@tuoran

#include<bits/stdc++.h>

using namespace std;

int main(){
    int n,k;
    scanf("%d%d",&n,&k);
    int Asum = 0,Bsum = 0;
    int cnt=0;
    for(int i=1;i<=n;i++)
    {
        if(i%k==0)
        {
            cnt++;
            Asum+=i;
        }
        Bsum+=i;
    }
    Bsum-=Asum;
    printf("%.1lf",double(Asum)/cnt);
    cout<<" ";
    printf("%.1lf",double(Bsum)/(n-cnt));
    return 0;
}

什么空格

by Scez @ 2024-08-21 19:24:49

@tuoran 两个答案之间

by Scez @ 2024-08-21 19:25:02

@tuoran 你都不看样例吗

by Scez @ 2024-08-21 19:25:34

@Scez

不过输入两遍似乎没影响

by Scez @ 2024-08-21 19:26:46

@tuoran 请输出这两类数的平均数，精确到小数点后1位，用空格隔开。
