During today's contest, I realized something weird about the new test case format: when you copy a test case by pressing the "copy" button, there's no newline at the end! This means that your first output will be on the same line as the last input, and you need to hit enter to get the last output to work. While this is obviously not a huge deal, it was a little weird to me and personally, I much preferred the old format.
Am I just a fool? Please tell me if so, I want to go back to the way things were! If this is just a feature of the new format, then please MikeMirzayanov: bring the newline back!
