During July 2025, Dongkyu Kim restructured and enhanced the uniljetstream/Intel7_codingTest_studyGroup repository, focusing on foundational improvements for the BitMask study. He established a clean directory structure, implemented a .gitignore for build artifacts, and developed bit manipulation utilities in C and C++. His work included solutions for common bitmask problems, such as counting set bits and checking powers of two, while also converting between binary and decimal formats. By updating documentation and clarifying contributor guidelines in Markdown, Dongkyu improved onboarding and maintainability. The changes emphasized code organization, version control with Git, and readiness for future feature development.
