USACO 2025 Open Contest Dataset

Dataset Description

The USA Computing Olympiad (USACO) is a prestigious algorithmic programming competition for high school students in the United States, consisting of four difficulty levels: Bronze, Silver, Gold, and Platinum. Each level contains a set of challenging problems that test algorithmic thinking and implementation skills, making USACO a valuable benchmark for evaluating the reasoning and problem-solving capabilities of large language models. This dataset contains problems and test cases from the USACO 2025 Open Contest.

Data Fields

Each problem in the parquet file contains:

name: Contest and difficulty level
problem_link: Official USACO problem link
test_data_link: Link to test data
solution_link: Link to official solution
problem_level: Difficulty level (bronze/silver/gold/platinum)
description: Full problem statement
input_format: Input specification
output_format: Output specification
samples: Sample test cases included in problem description
runtime_limit: Time limit in seconds
memory_limit: Memory limit in MB
solution: Official solution with explanation
