## README

This repository appears to be a collection of competitive programming solutions, including various contests and problem sets from platforms like AtCoder (ABC), Codeforces (CF), LeetCode (LC), NowCoder, and others. Each directory corresponds to a specific contest or platform, and each file represents a problem solution.

## 📁 Repository Structure

- **cpper/at/abc/**: Contains solutions for AtCoder Beginner Contest problems (e.g., `r411`, `r413`, `r414`, etc.).
- **cpper/cf/**: Contains solutions for Codeforces contests (e.g., `edu181`, `r1003_ak`, `r1027_e`, etc.).
- **cpper/lc/**: Contains solutions for LeetCode contests (e.g., `w453`, `w455`, etc.).
- **cpper/lq/**: Contains solutions for Lanqiao Cup contests.
- **cpper/nowc/**: Contains solutions for NowCoder contests, including weekly and monthly contests.
- **cpper/testc++/**: Contains test files for C++ code.

Each contest folder contains multiple Java or C++ files (`a.java`, `b.java`, etc.), each representing a problem from that contest.

## 🧠 Key Features

- **Diverse Problem Coverage**: Solutions from multiple competitive programming platforms.
- **Well-Structured Code**: Most files follow a consistent template for input/output handling and problem-solving.
- **Use of Algorithms and Data Structures**: Includes implementations of algorithms like DFS, BFS, Union-Find, Segment Trees, and more.
