Over four months, Taekyu Kim developed a reusable competitive programming solutions library in the ssafy16codingteststudy/1st_algorithm repository, focusing on algorithms, data structures, and problem-solving efficiency. He implemented advanced techniques such as Dijkstra’s algorithm, segment trees, and KMP-based string matching in Java and SQL, addressing graph traversal, dynamic programming, and string manipulation challenges. His work included optimizing shared taxi fare calculations, balancing queue sums with prefix sums, and validating Tic-Tac-Toe board states. By refactoring directory structures and unifying algorithm templates, Taekyu improved code maintainability and onboarding, while also delivering analytics-ready SQL queries for sales aggregation and reporting.
