During March 2025, Daeun Je developed the initial skeleton for Week 1 Problem 1 in the hyemi0622/algorithm repository, focusing on establishing a runnable Java class as a foundation for future problem-solving tasks. The work involved creating a main method that outputs 'HellO', serving as a placeholder to validate the development environment and ensure smooth execution. By emphasizing clean class design and basic console I/O, Daeun enabled rapid iteration and consistent progress tracking for subsequent algorithm challenges. The contribution did not address bug fixes but provided a clear, ready-to-extend structure, demonstrating proficiency in Java and methodical problem-solving skills.
