Oct 1, 2025October 2025 (2025-10) - Consolidated and delivered robust algorithms across Ssafy_Algo_Study. Finalized the BOJ 1992 Quad-Tree Image Compression solution with DFS, removing superseded implementations; implemented BOJ 22866 Skyline Visibility with a two-pass stack-based approach; delivered Java-based BOJ 24337 Array Construction; and implemented BOJ 14916 Minimum Coin Change with 2 and 5 unit coins. These efforts reduced maintenance burden, improved performance, and established reusable patterns for future challenges.

Jul 1, 2025July 2025 performance summary for Jihye511/Ssafy_Algo_Study. Expanded the algorithmic toolkit with eight feature implementations across DP, greedy, binary search, DFS, and string processing (BOJ 13305, 20920, 2512, 21921, 1515, 19941, 17484, 20310). Key deliveries include: optimal gas-price strategy (13305), budget cap via binary search (2512), greedy matching (19941), maximum subarray with fixed size (21921), subsequence-based integer construction (1515), lexicographic deletions optimization (20310), and supporting problems (17484, 20920). No explicit bugs reported; focus on robustness and performance, with edge-case handling (e.g., 'SAD' in 21921) and multi-commit refinements (20310). Technologies/skills demonstrated: algorithm design, performance tuning, and clear commit hygiene. Business value: provides a reusable, high-value algorithm library enabling faster decision-support and scalable problem solving across domains.
