Jin worked on the JeongEon8/AlgorithmStudyinGumi repository, developing a suite of grid-based and modular algorithmic solutions over two months. Using Java, he implemented BFS-based algorithms for maze shortest-path, grid-connected components, and combinatorial bridge-building, focusing on reusable and testable code. He extended the library with efficient HashSet and HashMap-based solutions for problems like Knight’s Move, Number of Islands, and Melon Farm, as well as several standalone challenges. Jin emphasized modular design and disciplined version control, resulting in a scalable framework that accelerates future problem coverage. His work demonstrated depth in algorithm design, data structures, and problem-solving methodology.
