Greetings, esteemed Codeforces community!

As an avid participant on this platform, I've found myself proficient in solving A and B level problems, yet I often struggle when attempting the more challenging C and D level tasks. Despite my best efforts, I frequently encounter the dreaded "Time Limit Exceeded" verdict.

I'm reaching out to seek guidance from fellow Codeforces enthusiasts who have successfully navigated through these higher difficulty problems. What strategies do you employ to enhance efficiency when tackling C and D level challenges? How do you approach problem-solving, algorithm design, and code optimization to ensure timely execution within the given constraints?

Furthermore, I'm curious to learn about effective practice strategies for honing skills specifically geared towards solving C and D level problems. How do you structure your practice sessions, and what resources do you find most beneficial in preparing for these challenges?

Any insights, tips, or personal experiences you can share would be immensely appreciated. Let's embark on this journey together and strive towards mastering the art of solving Codeforces C and D problems with finesse and efficiency.

Thank you for your time and wisdom.

Warm regards, remonhasan
