Feb 1, 2025February 2025 performance summary for hjk0761/Almumol. Delivered a focused set of algorithm challenges and a targeted codebase reorganization that enhances maintainability and reuse, with measurable impact on problem-solving capabilities and onboarding readiness. Key outcomes: - Expanded challenge coverage with five new programming problem solutions across arrays, strings, and grid logic, strengthening value proposition for practice and benchmarking. - Implemented a recursive Z-order curve traversal (BOJ 1074) to optimize spatial visitation patterns in 2D space. - Added BFS-based shortest bridge algorithm to identify minimal inter-island connections on grids, enabling efficient distance computations in grid problems. - Reorganized repository structure by creating a dedicated c++/baekjoon directory, improving navigation, build reliability, and collaboration. - Introduced additional programming challenges (numbers-string-and-words, secret-map, compression, and N-진수 게임) with multiple commits to extend problem-solving coverage and code reuse. Business value and impact: - Faster onboarding and contributor ramp-up due to clearer project structure and a reusable set of solutions. - Higher confidence in code quality and maintainability through modular organization and well-scoped commits. - Expanded problem-solving capabilities across key algorithmic domains, supporting benchmarking, learning, and competitive programming prep. Technologies/skills demonstrated: - C++ development, project organization, and build hygiene. - Algorithms: arrays, string parsing, BFS/DFS, recursion, and grid-based logic. - Problem-solving pattern extraction and code reuse for Baekjoon/Programmers-style challenges. - Version control hygiene with focused commits and descriptive messages.
