Developed and delivered a Number Theory Study Directory within the UngSangYoon/Algorithm_Study_FISA repository, establishing a structured foundation for algorithm study resources. The work included creating a detailed README.md in Markdown to outline study objectives and provide a direct link to the author’s profile, enhancing resource discoverability and onboarding for future contributors. A Python script was added to the new directory to validate its structure, demonstrating disciplined repository organization and file management practices. The approach focused on maintainability and reusability, laying groundwork for future expansion of study materials while leveraging Python scripting and Markdown documentation to support collaborative learning.
