这道题目很坑  卡输出格式   要求输出空行，但最后一行不要求多输出，害的我一直WA

这题目的意思就是求几个数的和，开始是代表有几组数据，以后每一行求一次和，然后输出

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