Edit: Problem fixed. It turns out that I output the answer in a separate function before I input and output the file, which causes the problem. Thanks for everyone that helps :)
Edit: I did write output file
I've been doing some past USACO Gold problems lately, but I have met some troubles regarding submission. Although my program outputs the correct answer, it keeps telling me that the answer is incorrect. I've met these kind of troubles before, so I thought its just a format issue. But no matter how I adjust the way I output the answer, it doesn't work.
For example, I have tried
cout << ans << "\n";
cout << ans << endl;
cout << ans << " ";
cout << ans; but non of them works.
Here are two screenshots:
Can someone please help me with that? I just don't want to run into these kind of troubles during real contest lol. Thanks!
