Oct 1, 2025October 2025 — Monthly summary for Jihye511/Ssafy_Algo_Study. Delivered a high-impact set of algorithmic features across multiple BOJ problems with strong focus on performance, robustness, and code quality. Highlights include stack-based nearest taller building (BOJ 22866) in O(n); constraint-based build sequence (BOJ 24337) with graceful handling of impossible cases; camera surveillance optimization (BOJ 15683) exploring orientations to minimize unmonitored area; DP-based coin change feasibility (BOJ 1943) with binary-count optimization; and codebase improvements including quadtree-based 2D compression (BOJ 1992) and 2D prefix sum-based subregion queries (BOJ 15724). A codebase reorganization plus a new DP addition for BOJ 14916 also progressed. Where applicable, edge-case robustness was improved and performance characteristics are reflected in the commits (ms timings). These efforts deliver tangible business value by enabling faster, more reliable problem-solving and promoting reusable implementation patterns for future challenges.
