During July 2025, this developer contributed to the Jihye511/Ssafy_Algo_Study repository by delivering two features focused on algorithmic problem solving and codebase maintainability. They implemented a fuel cost optimization solution for BOJ 13305 using a greedy algorithm, enabling efficient calculation of minimum travel costs by always selecting the lowest-priced gas station encountered. Additionally, they refactored the problem practice structure, renaming modules and preserving existing logic to improve code clarity and onboarding readiness. Their work leveraged Java and Python, emphasizing algorithmic thinking, data structures, and maintainable commit practices, which collectively enhanced runtime efficiency and reduced operational risk for future contributors.
