#include<stdio.h>

int comp(const void *,const void *);

int main(){
int i=0,t=0,n=0,j=0;
long int arr[100];
// printf(“enter the noo of test cases”);
scanf("%d",&t);
for(i=0;i<t;i++){
//printf(“enter the value of n”);
scanf("%d",&n);
if(n>=2){
//printf(“enter the sequence”);
for(j=0;j<n;j++){
scanf("%ld",&arr[j]);
}

     qsort(arr,n,sizeof(int),comp);
     printf("%ld",(arr[0]+arr[1]));

     }
     }

return 0;
}

int comp(const void *i,const void *j){
return *(int *)i- *(int *)j ;
}
