Code Practice Tool

The tool implements a focused code practice engine that exposes a catalog of problems, language support, and a sandboxed evaluation environment. It targets learners, students, and professional developers seeking structured practice and interview readiness.
Conceptually, problems map to unit-test style suites. User-submitted code is executed against predefined inputs within a sandbox, and results are validated against expected outputs. The system returns per-test-case results, a total score, and runtime metrics to guide refinement.
Audience and value: individuals pursuing self-directed learning, students preparing for coding interviews, educators assigning practice, and teams benchmarking developer readiness. Unique differentiators include reproducible progress tracking, scalable problem catalogs, language-specific feedback, and robust isolation for safe execution.
Core features and use cases include problem catalog with metadata, multi-language support, per-test-case evaluation, real-time scoring, hints, starter templates, and progress dashboards. Use cases span interview prep curricula, coursework supplementation, onboarding new engineers, and skill assessments for hiring.
