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

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

 

Sample Output

10156
