Your task is to calculate the sum of some integers.
Input
Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line.

Hint
提供一个参考程序：
C语言：
#include"cstdio" ///也可以使用 < >
int main()
{
int testcases;
int n,x,sum;
scanf("%d", &testcases);
while(testcases--)
{
scanf("%d", &n);
sum = 0;
while(n--)
{
scanf("%d", &x);
sum += x;
}
printf("%d\n", sum);
printf("\n");
}
return 0;
}
C++:
#include"iostream" ///也可以使用 < >
using namespace std;
int main()
{
int testcases;
int n,x,sum;
cin >> testcases;
while(testcases--)
{
cin >> n;
sum = 0;
while(n--)
{
cin >> x;
sum += x;
}
cout << sum << endl;
cout << endl;
}
return 0;
}
