It's quite clear that cheating has significantly increased in today's competition. The situation keeps getting worse every now and then. What used to be a competitive programming contest now looks more like a competition for who can cheat better. I know many people have talked about this before, but today, the solutions up to the fourth problem were readily available on YouTube. It's become a collective cheating party, and spare me the foolish advice to focus on solving and improving myself. My first variable in problem A you! Here, we are competing with each other, not with ourselves.
