C语言AC代码：

#include <stdio.h>
int main()
{
    int n,m,x,sum;
    scanf("%d",&n);

        while(n--)
        {
            scanf("%d",&m);
            sum=0;
            while(m--)
            {
                scanf("%d",&x);
                sum+=x;
            }
            printf("%d\n",sum);
        }

    return 0;
}

Java AC代码：

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);

		int n = sc.nextInt();
		while(n-->0){
			int m = sc.nextInt();
			int sum = 0;
			while(m-->0){
				int x = sc.nextInt();
				sum += x;
			}
			System.out.println(sum);
		}
	}
