I was getting this error in some of the problems and my solution was getting Memory Limit Exceeded on Test 1 or Wrong Answer on Test 1. But after adding below lines my solutions got accepted.
ifstream cin("input.txt"); ofstream cout("output.txt");
Problem253 A
If you define cin and cout as file streams in main function, they are not visible in the auxiliary function. So the first submission tries to read from the standard input instead of file stream.
