2：简单很多，主要我也不知道我咋想到的！！！

#include <stdio.h>
int main(void)
{
    int a, i, n, m, b, s;
    while (scanf("%d %d", &n, &m) != EOF && n<=100)
    {
        a = 2;
        b = n%m;
        s = n / m;
        for (i = 0; i < s; i++)
        {
            printf("%d", a + m - 1);
            if (i < s - 1)
                printf(" ");
            a = a + m * 2;
        }
        if (b != 0)
        {
            printf(" %d", a);
        }
        printf("\n");
    }
    return 0;
}
