## Description ##

还有一些输入是以上几种情况的组合,具体根据题目对前面几种情况进行组合  
比如题目要求是多组测试数据  
每组测试数据首先输入一个整数n(如果n=0就表示结束） 然后再输入n个整数  
这类题目输入格式如下：

int main()
    
    {
    
        int n,i;
    
        while(scanf("%d",&n)!=EOF && n!=0)
    
        {
    
             for(i=1;i<=n;i++)
    
             { 
    
                  ....//每次输入一个数，共循环n次，需要的时候做其他处理
    
             }
    
    
    
        }
    
    }

## Input ##

Input contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input and this test case is not to be processed.

## Output ##

For each group of input integers you should output their sum in one line, and with one line of output for each line in input.

## Sample Input ![5f8f312f51791b8bb0ed0ae07c2ffa43.gif][] ##

4 1 2 3 4
    5 1 2 3 4 5
    0

## Sample Output ##

10
    15

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