if i keep br.close() in the code, codechef judge gives runtime error.

Can anyone please help.

Thank you very much

Brother, remove .close(). When a file is “opened,” the OS marks the file as locked, generally so it can’t be deleted by other processes while it’s being used. x.close() undoes the lock, allowing the OS and other processes to do what it wishes with the file. I’ve answered it in recent post : http://discuss.codechef.com/questions/53366/java-closing-bufferedreader & your corrected code: http://ideone.com/GkbF9p
