Dec 1, 2025December 2025 (Problem-solve-study/code-store) delivered a focused set of business-relevant algorithmic capabilities that boost problem-solving efficiency, routing performance, and cost optimization. Key achievements include: - BOJ 1222 N/E variants: added solutions for multiple subproblems from BOJ 2014 contest 1222 (N and E variants). Commits: 0c63c82859c91ef1cdcebe6656beb0092300d670; ce4b441f2c77b88a544f599954782ab933d02cfc; e6f47e1c9d93d6c5b3426727bf917a48ce02a642. - BFS-based pathfinding: implemented standard shortest path with one-wall destruction, multisource BFS, and constrained BFS for linear-building layouts. Commits: 2245fde1a2efe26ea4bd37c7b70dfd5d2502c209; eb830e8dcefb108fc8ac04c6f27bb12d34afec95; 76c2ecd35433abca31b780338f95ba1243d14a2b. - Graph distance computations (Dijkstra): robust shortest-path and distance calculation utilities across BOJ problems. Commits: 6e47a3bdf4c39f6186943ba375d28174f9284ddc; e294b976f80aca7c6e50b36230baa597ae538192. - Dynamic programming: min-cost to purchase exactly N cards with given packs. Commit: 0ae9c730c26cc2071d2a10df03568a845f5b0c5a. - Pattern/string/matrix tooling: matrix pattern counting and longest non-palindromic substring enhancements. Commits: d2c207c27c8e7ea1d5e2c677a5503159b0e906e5; 6acca22d62f58e5a9d1869b0c8d236ca762f385c. This month also reinforced code quality with test scaffolding and documentation across these modules, accelerating onboarding and maintenance.
