During two months contributing to DaleStudy/leetcode-study, Yuitfhk developed a reusable Algorithm Practice Library in Java, implementing 11 core algorithms spanning arrays, strings, dynamic programming, and data structures. Their work included solutions for problems such as two sum, word search using depth-first search, merging sorted linked lists, and longest increasing subsequence with binary search and DP. Yuitfhk emphasized clean code practices, improving formatting and repository hygiene to support maintainability and onboarding. By focusing on practical algorithm implementations and code readability, they enhanced the repository’s value for interview preparation and coding practice, demonstrating depth in algorithm design and problem-solving skills.

Nov 1, 2025November 2025: Delivered a reusable Algorithm Practice Library and code quality improvements for DaleStudy/leetcode-study. Key outcomes include core algorithm implementations across arrays, strings, and dynamic programming with practical problems (e.g., two sum, top-k frequent elements, longest consecutive sequence, house robber, valid anagram, climbing stairs, valid palindrome, number of 1 bits, maximum subarray). Introduced code quality enhancements (newline endings, formatting hygiene) and fixed a bug in the Two Sum solution by removing an unnecessary map.get(pair) condition. This work accelerates interview prep, improves code readability, and strengthens maintainability of the repository.
