### Dataset Summary |
|
|
|
|
|
- **This dataset is an extension of the one found** [here](https://huggingface.co/datasets/open-r1/codeforces-submissions) adding the problem data for each submission, including things like the statement, title, difficulty, etc... |
|
|
- This dataset aims to **facilitate the creation of sophisticated, multi-turn dialogue datasets focused on coding** |
|
|
that could be used for **training reasoning Large Language Models (LLMs)**, particularly for **Supervised Fine-Tuning (SFT) and Knowledge Distillation** techniques. |
|
|
- It also serves as a **robust foundation for problem-solving** in Large Language Models (LLMs). |
|
|
- The dataset includes both **accepted and failed solutions** from [Codeforces](https://www.codeforces.com) contests. |
|
|
- It covers contests up to contest **Codeforces Round 1004** **(Feb 11, 2025)**. |
|
|
- In total, it features **10385 unique problems**, **1879 contests** and **11,949,042 submissions** across over **60 different programming languages** (including different compiling environments for each language). |
|
|
|
|
|
(**The dataset is not accessible to the public, please do not contact me regarding its access.**) |
