During January 2026, work focused on the JeongEon8/AlgorithmStudyinGumi repository, delivering three algorithmic features in Java. A Sudoku solver was developed using backtracking and bitmasking, with documentation updated to clarify the depth-first search and bit manipulation approach. A dynamic programming solution for palindromic range queries was implemented, leveraging preprocessing to enable constant-time responses for range checks. Additionally, the codebase saw a refactor of the subarray minimum length calculation, improving readability and maintainability. Throughout the month, minor fixes and refactors were made to enhance stability, with no major defects reported, demonstrating a methodical and detail-oriented engineering approach.
