题意：中文，忒麻烦了。

代码：

# include <stdio.h>


int main ()
{
    int n, m, flag ;
    int i, sum, cnt ;
    while (~scanf ("%d%d", &n, &m))
    {
        flag = 0 ;
        cnt = 0 ;
        sum = 0 ;
        for (i = 1 ; i <= n ; i++)
        {
            sum += i*2 ;
            cnt ++ ;
            if (cnt == m)
            {
                if (flag == 0) flag = 1 ;
                else printf (" ") ;
                printf ("%d", sum/m) ;
                cnt = 0 ;
                sum = 0 ;
            }
        }
        if (cnt != 0)
        {
            if (flag == 0) flag = 1 ;
            else printf (" ") ;
            printf ("%d", sum/cnt) ;
        }
        printf ("\n") ;
    }
    return 0 ;
}
