During February 2026, contributed to the GDG-IGDTUW/DSA-1 repository by developing two core features focused on algorithmic robustness and maintainability. Built a recursive string-to-integer parser in Java that handles leading spaces, optional signs, and integer overflow, enhancing input reliability for downstream processes. Also implemented a dynamic programming solution for the Stone Game II problem, enabling optimal computation of the maximum stones the first player can collect. Both features leveraged Java’s strengths in algorithm design, recursion, and dynamic programming, reflecting a methodical approach to problem-solving and code quality. No bugs were reported or fixed during this period, indicating stable delivery.
