贴上代码↓↓↓

#include <iostream>
using namespace std;

void main()
{
	int n;
	while (cin >>n)
	{
		for (int i = 0; i < n; i++)
		{
			int a,b,s=0;
			cin >> a;
			for (int j = 0; j < a; j++)
			{
				cin >> b;
				s += b;
			}
			if (i!=n-1)cout << s << endl << endl;
			else cout << s << endl;
		}
	}
}
