Your task is to calculate the sum of some integers.

Input contains multiple test cases, and one case one line. Each case starts with an integer N( 0 < N<=500 ), and then N integers follow in the same line.

For each test case you should output the sum of N integers in one line, and with one line of output for each line in input.

提供一个参考程序：

C语言：
#include"cstdio"  ///也可以使用 < >
int main()
{
    int n,x,sum;
    while(scanf("%d", &n) != EOF)  /// EOF: end of file  文件结束标志
    {
        sum = 0;
        while(n--)
        {
            scanf("%d", &x);
            sum += x;
        }
        printf("%d\n", sum);
    }
    return 0;
}

C++:
#include"iostream"  ///也可以使用 < >
using namespace std;
int main()
{
    int n,x,sum;
    while(cin >> n)
    {
        sum = 0;
        while(n--)
        {
            cin >> x;
            sum += x;
        }
        cout << sum << endl;
    }
    return 0;
}
