#include<stdio.h>
void main()
{
 int i,j,k,l,sum[100],su,m,count;
 m=0;su=0;count=0;
 scanf("%d\n",&i);
    for(j=0;j<i;j++)
 {
  scanf("%d",&k);
  for(l=0,m=0,su=0;l<k;l++)        对于m=0,su=0应该在此赋值 由此来清空上一次循环留下的数
  {
   scanf("%d",&m);
   su=su+m;
   sum[j]=su;
  }
  sum[j]=su;
  count++;
 }
 for(j=0;j<count-1;j++)
  printf("%d\n",sum[j]);
 printf("%d",sum[count-1]);
}
