Baekjoon is a collection of competitive programming problem solutions for the Baekjoon Online Judge platform.
The repository addresses the need for reference implementations when preparing for coding interviews and competitive programming contests. It provides solutions to problems from Baekjoon Online Judge, covering algorithmic topics including graph traversal, disjoint-set data structures, mathematical algorithms, and string processing with tries. The solutions are implemented primarily in C++, offering working code that demonstrates how to approach and solve each problem.
This collection suits developers preparing for technical interviews or programming competitions who want to study existing solutions and understand different algorithmic approaches. It works best as a learning resource alongside active problem-solving practice rather than as a substitute for working through problems independently. The breadth of topics covered—spanning fundamental algorithms like BFS to more specialized structures like disjoint-set unions—makes it useful for building a foundation across multiple problem categories.
The project maintains a straightforward structure focused on accumulating solutions without apparent release cycles or formal versioning. Development activity centers on adding new problem solutions to the collection rather than refactoring or maintaining existing code. The repository does not show signs of active issue management or community contribution workflows, operating instead as a personal reference archive.
