A+B for Input-Output Practice (VIII)

Problem Description

Your task is to calculate the sum of some integers.

Input

Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line.

Output

For each group of input integers you should output their sum in one line, and you must note that there is a blank line between outputs.

Sample Input

34 1 2 3 45 1 2 3 4 53 1 2 3

 

Sample Output

10156

注：两行之间输出一个空行，最后一行没有空行！

代码：

#include<stdio.h>int main(){    int n,m,i,j,sum,a;    scanf("%d",&n);    for(i=0;i<n;i++){        sum=0;        scanf("%d",&m);        for(j=0;j<m;j++){            scanf("%d",&a);            sum+=a;        }        printf("%d\n",sum);        if(i!=n-1)            printf("\n");    }    return 0;}
