@python18

你们是商量好的吗都错差不多

#include<iostream>
#include<cstdio>
using namespace std;
int n,k,cnt1=0,cnt2=0;
double ans1,ans2,sum1,sum2;
int main(){
    cin>>n;
    cin>>k;
    for(int i=1;i<=n;i++){
        if(i%k==0){
            sum1+=i;
            cnt1++;
        }else{
            sum2+=i;
            cnt2++;
        }
    }
    ans1=sum1/cnt1;
    ans2=sum2/cnt2;
    printf("%.1lf %.1lf",ans1,ans2);
    return 0;
}
