# BEST Dataset

This repository hosts the benchmark data for BEST: Benchmarking Efficiency in Space and Time for LLM-Generated Code.

## Files

- `data.csv`: C++ benchmark metadata.
- `data_py.csv`: Python benchmark metadata.
- `test_cases/*.tar.zst`: sharded test cases.
- `checksums.sha256`: SHA-256 checksums for all files in this repository.

## Layout

Place the files under the BEST repository's `data/` directory:

```text
data/data.csv
data/data_py.csv
data/test_cases/<problem_id>/<case_id>.in
data/test_cases/<problem_id>/<case_id>.out
```

The test case archives preserve `test_cases/<problem_id>/...` paths. Extract them under `data/` to restore the expected layout.
