AI Coding Challenges

Original, self-contained coding exercises that demonstrate benchmark design, precise requirements, reference implementations, and automated testing.

Challenges

Python: Normalize Event Records

Normalize inconsistent event dictionaries into a deterministic schema while validating required fields.

JavaScript: Summarize Review Scores

Aggregate reviewer scores by category without mutating the input.

Design principles

• Unambiguous task statements
• Deterministic expected behavior
• Edge-case coverage
• Clear failure messages
• Original examples without proprietary material
