#include<stdio.h>

int main(void)
{
    int n,i;

    printf("# Cards  Overhang\n");
    while (scanf("%d", &n) != EOF)
    {
        double result = 0.0;
        for (i = 1; i <= n; ++i)
            result += 1 / (double)i;
        result /= 2.0;
        printf("%5d%10.3lf\n", n,result);
        // %m.nf：輸出共佔m列，其中有n位小數，如數值寬度小於m左端補空格。
    }

    return 0;
}

如此水題居然提交n多遍，也是醉了~~
