+## Welcome to the open source code repository on Gitee platform!
+
+This repository contains C++ solutions for a variety of common algorithm problems, including binary search, sliding window, two pointers, monotonic stack, enumeration, and other data structure-related topics. It is suitable for algorithm learning and as a reference for practice on platforms like LeetCode.
+
+## Repository Structure Description
+
+- **Binary search**: Problems related to binary search, such as `34.cpp`, `35.cpp`, `1146.cpp`, and `2529.cpp`.
+- **Dichotomy answers**: Problems involving binary search on answers, such as `1011.cpp`, `1283.cpp`, `1482.cpp`, and others.
+- **Double sequence with double pointers**: Problems involving two pointers on two sequences, such as `1023.cpp`, `2109.cpp`, `2540.cpp`, and others.
+- **Enumeration from the middle**: Problems that involve enumeration from the middle, such as `1930.cpp`, `2909.cpp`, `3128.cpp`, and others.
+- **Enumeration**: General enumeration problems, such as `1010.cpp`, `1512.cpp`, `2441.cpp`, and others.
+- **Fixed-length sliding window**: Problems involving fixed-length sliding window techniques, such as `1052.cpp`, `1297.cpp`, `1423.cpp`, and `2269.cpp`.
+- **Grid chart_BFS & Grid chart_DFS**: Breadth-First Search (BFS) and Depth-First Search (DFS) problems on 2D grids, such as `542.cpp`, `1020.cpp`, `200.cpp`, and others.
+- **Grouped-cycling**: Grouped loop problems, such as `1446.cpp`, `1577.cpp`, `1759.cpp`, and others.
+- **Single sequence with two pointers**: Two pointer problems on a single sequence, such as `11.cpp`, `1089.cpp`, `15.cpp`, and others.
+- **Stack**: Problems related to stack algorithms, such as `1172.cpp`, `1472.cpp`, `895.cpp`, and `1441.cpp`.
+- **Three pointers**: Three-pointer problems, such as `2367.cpp`, `2444.cpp`, `795.cpp`, and others.
+- **Indefinitely long sliding window**: Variable-length sliding window problems, such as `3.cpp`, `76.cpp`, `438.cpp`, and others.
+
+## Installation and Execution
+
+All code is written in C++ and can be run using standard C++ compilation tools. For example:
+
+```bash
+g++ -std=c++11 -o solution 35.cpp
+./solution
+```
+
+## Usage
+
+Each `.cpp` file contains a `class Solution`, where the `public` functions correspond to solutions for LeetCode problems. You can directly copy the code into the LeetCode platform for testing.
+
+## Contribution
+
+Pull requests are welcome to improve solutions or add new problem-solving code. When submitting, please follow these guidelines:
+
+1. Code should use standard C++ syntax.
+2. Function names within the `class Solution` should match those in the original problem.
+3. Comments should preferably be in Chinese, and be clear and concise.
+4. Please provide the problem number and solution idea when submitting.
+
+## License Agreement
+
+The code in this repository follows the LeetCode problem license agreement. There are no special licensing restrictions; it is intended solely for learning and research purposes.
+
+## Contact
+
+If you have any questions, please contact the repository maintainer or submit an Issue.
