This repository serves as a collection of solutions to various problems from AtCoder. Its purpose is straightforward: to provide an organized study record, make it easy to revisit past work, and help identify common problem-solving patterns found in programming contests.
- Document solutions from different AtCoder contest categories.
- Summarize the core ideas and solution steps for each problem clearly and concisely.
- Provide a reference for reviewing and strengthening understanding of algorithms and data structures.
- Present clean, readable, and easy-to-follow implementations.
All solutions are written in C++. The language is chosen for its strong performance and flexibility in competitive programming environments. Nevertheless, the main focus remains on reasoning and problem-solving approaches rather than on any language-specific features.
