Newbies, pupils, and specialists on Codeforces often lack skill due to a fundamental failure to engage deeply with the core principles of competitive programming. Newbies typically rush through basic concepts without truly internalizing them, leading to shallow understanding. Pupils often plateau because they focus too much on solving problems within their current comfort zone, neglecting to expand their knowledge of more advanced algorithms and data structures. Specialists, despite being more experienced, often become complacent, relying on repetitive problem types and avoiding the more complex, diverse challenges that would push their skills further. Overall, many fail to invest in deliberate practice, struggle to adapt to a variety of problem-solving approaches, and rarely step outside their limited scope, resulting in slow or stagnant skill growth. I also hate Codeforces Round 985 as I am from the future and I know it is gonna be a very low quality round judging from the score distribution and announcement. I encourage anyone to avoid taking this round to avoid negative delta.
