Input contains multiple test cases, and one case one line. Each case starts with an integer N, and then N integers follow in the same line.

[align=left]Output[/align]
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.

[align=left]Sample Input[/align]

4 1 2 3 4
5 1 2 3 4 5

C语言AC代码：

#include <stdio.h>
int main()
{
int n,x,sum;
while(scanf("%d",&n)!=EOF)
{
sum=0;
while(n--)
{
scanf("%d",&x);
sum+=x;
}
printf("%d\n",sum);
}
return 0;
}

Java AC代码：

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while(sc.hasNext()){
int n = sc.nextInt();

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

}
