Features
CP2022 (likely referring to *Codeforces Round #2022*) featured:
- Div. 1 + Div. 2 combined contest with problems for all skill levels.
- 6–8 problems, typically with increasing difficulty (A–F/G).
- Dynamic scoring: Points decreased over time (e.g., 500–1000 for easy, 1500–3000 for hard).
- Hacks/pretests: Open hacking phase post-contest (for Educational/Div. 2 rounds).
- 2–2.5 hours duration, with penalties for incorrect submissions (-50 points).
- Standard ICPC rules: No partial points, all-or-nothing test cases.
Exact details vary by round; check the [announcement](https://codeforces.com/blog/entry/107415) for specifics.
