Jun 1, 2025June 2025 — Focused feature delivery and reliability improvements for Problem-solve-study/code-store. Delivered major features including a Dynamic Programming solver for BOJ 2226 (with BigInteger support for large counts), a grid-based simulation for BOJ 8972 (Crazy Robot), and a Greedy Meal Optimization approach for BOJ 23559 to minimize memory usage while respecting budget. Documentation updated for June 4th problems, and a reliability fix for the auto-commit script following README formatting changes. These efforts reduced time-to-solve for complex problems, improved run-time performance and stability, and streamlined repository maintenance.
