一直没过不是你的错，是因为

最后一个输出不用换行了。。。

 

#include
      
       int main(){    int n;    int m;    scanf("%d",&m);    while(m--)    {        scanf("%d",&n);        int sum=0;        while(n--)    {        int a;        scanf("%d",&a);        sum+=a;    }    printf("%d\n",sum);    if(m) printf("\n");    }    return 0;}
