Over four months, Jisoo Yoon developed a robust suite of algorithmic solutions in the ssafy16codingteststudy/1st_algorithm repository, focusing on problem-solving depth and code maintainability. Leveraging Java and SQL, Jisoo implemented features spanning dynamic programming, graph algorithms, and data aggregation, including queue balancing, shortest-path fare optimization, and grid-based simulations. The work incorporated advanced techniques such as Dijkstra’s algorithm, segment trees, and disjoint set union, with careful attention to code documentation and modularity. By emphasizing reusable patterns and clear commit traceability, Jisoo established a scalable foundation for coding assessments, technical interviews, and rapid prototyping in competitive programming contexts.
