我的代码：

# include <bits/stdc++.h>
using namespace std;
int n, k, sum;
int main () {
    scanf ("%d%d", &n, &k);
    for (int i = k; i <= n; i += k)
        sum += i;
    printf ("%.1f ", double (sum) / (n / k)); 
    sum = (1 + n) * n / 2 - sum;
    printf ("%.1f\n", double (sum) / (n - n / k));
    return 0;
}

@maguangyin 你这代码有种说不出的怪

我也看着很怪，很乱
