Developed a foundational Java starter template for the hyemi0622/algorithm repository, focusing on establishing a consistent entry point for future problem-set solutions. The work centered on creating a reusable Hello World program, encapsulated in a single Java file, to streamline onboarding and ensure reliable baseline testing for subsequent tasks. By prioritizing problem solving and template design, the developer provided a traceable, repeatable starting point that supports efficient development workflows. No bug fixes were addressed during this period, as the primary objective was to lay the groundwork for future feature implementation using Java and standard version control practices within the repository.
