A+B for Input-Output Practice (IV)

Problem Description

Your task is to Calculate the sum of some integers.

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

4 1 2 3 45 1 2 3 4 50 

 

Sample Output

1015

注：每组数据前都有一个数提示，当一行第一个数为0，输入结束。

代码：

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