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 T;
scanf("%d",&T);
while(T--)
{
int i,n,s,a;
scanf("%d",&n);
s=0;
for(i=1;i<=n;i++)
{
scanf("%d",&a);
s=s+a;
}
printf("%d\n\n",s);
}
return 0;
}

而你每行后面都输出空行了，所以PE
可以添加个标记，只要不是第一组数据，就先输出个空行再输结构就可以了，代码如下
#include <stdio.h>
int main()
{
int T;
int flag; //这里
flag=0;
scanf("%d",&T);
while(T--)
{
int i,n,s,a;
scanf("%d",&n);
s=0;
for(i=1;i<=n;i++)
{
scanf("%d",&a);
s=s+a;
}
if(flag)
printf("\n");
else
flag=1;
printf("%d\n",s);
}
return 0;
}
