Fatimah developed a deterministic subset-generation utility for the GDG-IGDTUW/DSA-1 repository, focusing on algorithm design and C++ programming. She implemented a backtracking-based approach that efficiently generates all possible subsets of a set, including logic to handle duplicate elements by sorting the input, ensuring no redundant subsets are produced. Alongside this feature, Fatimah addressed a file management issue by correcting a filename inconsistency, improving repository structure and clarity. Her contributions emphasized code reliability and maintainability, supporting easier onboarding and review processes. The work demonstrated depth in C++ and backtracking, with attention to repository hygiene and collaborative development practices.
