{
    int n = 0;
    int num = 0;
    int sum = 0;
    int temp = 0;
    while(scanf("%d", &num) != EOF)
    {
        while(num--)
        {
            scanf("%d", &n);
            sum = 0;
            while(n--)
            {
                scanf("%d", &temp);
                sum += temp;
            }
            printf("%d\n", sum);
        }
