HDOJ 1096 A+B for Input-Output Practice (VIII)

#include <iostream>
using namespace std;

int main()
{
int n;
cin >> n;
for(int i=0;i<n;i++)
{
int m,s=0;
cin >> m;
while(m--)
{
int t;
cin >> t;
s+=t;
}
cout << s << endl;
if(i!=n-1)//问题就在这儿，以前不写这个判断
cout << endl;
}
return 0;
}


这道题很水，但是就是AC不了，输入输出正确，格式也毫无问题。这种问题没啥思考价值就去网上查了下，发现最后一个输出不用换行！！！坑爹QAQ

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

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