In May 2025, Hyeonho developed a Competitive Programming Problem Solver Suite for the cold-weather-coding-test-study/coding-test-certification repository, focusing on expanding practice tooling for coding assessments. He implemented four problem solutions, including a breadth-first search algorithm for island counting, a simulation of Arduino versus player movement, and a string-based maximum distance calculation. Using Java, he applied data structures such as HashSet, LinkedList, and Queue to create a reusable solver framework that supports rapid validation and future problem additions. Hyeonho maintained clear version control practices, delivering a focused feature set that deepened the repository’s support for coding test preparation.

Month: 2025-05 — Key deliverable: Competitive Programming Problem Solver Suite added to cold-weather-coding-test-study/coding-test-certification, featuring four problem solutions. Notable implementations include BFS-based island counting, a game simulation of Arduino vs. player movement, and a string-movement-based maximum distance calculation. Commit 328998eb4b4e81fd35c7a98fab41e8e20022f868 ("9주차 코테"). No major bugs fixed this month. Impact: expands practice tooling for coding certifications, enabling faster validation and broader problem coverage, contributing to higher-preparedness for assessments and interviews. Skills demonstrated: algorithm design (BFS), simulation modeling, string processing, and strong Git/version-control discipline across a focused feature set.
