Problem Description
Your task is to calculate the sum of some integers.
 

Input
Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line.
 

Output
For each group of input integers you should output their sum in one line, and you must note that there is a blank line between outputs.
 

Sample Input
3
4 1 2 3 4
5 1 2 3 4 5
3 1 2 3
 

Sample Output
10

15

6
 
#include<stdio.h>
int main()
{
    int n,m,i,a,sum;
    scanf("%d",&n);
    while(n--)
    {
        while(scanf("%d",&m)!=EOF)
        {
            sum=0;
            for(i=1;i<=m;i++)
            {
                scanf("%d",&a);
                sum+=a;
            }
            printf("%d\n\n",sum);
        }
    }
    return 0;
}
这是我的代码，为什么老是提交上去说的是格式错误，可是我不知道错哪里，求解

结尾多了一个\n

本来就是要空两行的

答案之间需要一个空行，谁说了答案最后也需要一个空行

#include<stdio.h>
int main()
{
    int n,m,i,a,sum;
    scanf("%d",&n);
    while(n--)
    {
        while(scanf("%d",&m)!=EOF)
        {
            sum=0;
            for(i=1;i<=m;i++)
            {
                scanf("%d",&a);
                sum+=a;
            }
            if(n!=0)
                printf("%d\n\n",sum);
            else
                printf("%d\n",sum);
        }
    }
    return 0;
}
改成这样也是格式错误啊

#include<stdio.h>
int main()
{
    int n,m,i,a,sum;
    scanf("%d",&n);
    while(n--)
    {
        scanf("%d",&m);
            sum=0;
            for(i=1;i<=m;i++)
            {
                scanf("%d",&a);
                sum+=a;
            }
            if(n!=0)
                printf("%d\n\n",sum);
            else
                printf("%d\n",sum);
    }
    return 0;
}

为什么不能用while(scanf("%d",&m)!=EOF)
