include <iostream>

using namespace std;
int main() { ifstream input("input.txt"); ofstream output("output.txt"); string str; int num, sum = 0, div = 0; while(getline(input, str)){ string buf; istringstream iss(str); while(iss >> buf){ istringstream ss(buf); ss >> num; sum += num; div++; } output << sum/div << " "; sum = 0; div = 0; } return 0; }
That is the code I wrote and from what I can tell is will give the correct answer However the answers that I get a wrong (and not an off by one) and I think the checker for this question is broken Any suggestions?
Hi,
If I try your code with the example input data, it gives the answer 3 3 10 0 when the expected answer is 4 15 1.
Here's a few things to look at.
The first line of input contains the number of test cases.
Each test case has a 0 marking the end. This should not be included in calculations.
Try to get your code to read from stdin and write to stdout. It makes it a lot easier to help you.
I can't see that your code does rounding as required by this problem.
