The Codeforces Survival Guide: Losing Rating Like a Pro

Salam Codeforces!

Ah, Codeforces—the place where dreams of grandmaster glory turn into rating drops faster than you can debug a segfault. Whether you’re here to improve or just coping with another brutal contest, welcome! Let’s talk about how to lose rating in the most legendary way possible.

Step 1: Confidence is Everything (Until It Isn’t)

Solved a 1200-rated problem? Boom! You’re a genius. Enter the next contest with full swagger, tell your friends you're gonna get +200 rating, then get slapped back to reality by pretest 2.

Step 2: Who Needs Edge Cases?

Constraints? Who cares. Edge cases? Not your problem. Submit your first instinctive solution and watch in horror as it fails on the simplest counterexample. Then spend 20 minutes debugging only to realize you forgot to handle negative numbers again.

Step 3: Intuition is a Trap

"This feels like a greedy problem!" Famous last words. Codeforces problems love to trick you into overthinking or, worse, underthinking. Turns out, it needed DP, graphs, or some obscure math trick that only grandmasters whisper about.

Step 4: System Tests = Instant Regret

Pretests passed? Nice. Now sit back and enjoy the anxiety rollercoaster as system tests destroy your confidence. Your O(n^2) solution seemed fine? Too bad, the hidden test case just turned it into an infinite loop.

Step 5: Excuses, Excuses

Rating drop? Not your fault! - "The problems were weird." - "My laptop was lagging." - "Hackers are ruining the game." - "The contest was clearly biased." - "My cat stepped on my keyboard."

Conclusion: The Cycle Never Ends

We all suffer together, my friend. Keep grinding, keep coping, and keep telling yourself next time will be better. Because that’s the real competitive programming mindset. Now, excuse me while I go question my life choices after three WAs on an 800-rated problem. See you in the next contest!
