# wzj52501/awesome-competitive-olympiad-algorithms

> An archive of original algorithmic contest problems and lecture notes spanning NOIP to NOI and ACM-ICPC level. Each problem includes a statement, a reference C++ solution, and an editorial with correctness proof and complexity analysis.

- Magnitude: 0.9 out of 10 — Steady

## Useful for

- Prepare for informatics olympiads by studying editorials of NOI and ACM-ICPC level problems.
- Use lecture slides for self-study of algorithms and data structures.
- Test your solutions against the official test data from the AwesomeAlgorithms_SetterData archive.

## Why it’s here

- 0 stars so far today, about 3 expected by the end of the day.
- The repository is 17 days old and already has 238 stars.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
