Welcome to my Data Structures and Algorithms (DSA) repository! This repository is a personal project where I document and solve various problems related to data structures and algorithms. It's a reflection of my journey in mastering these fundamental concepts and enhancing my problem-solving skills.
- Problems: A collection of solved problems categorized by data structures and algorithms.
- Solutions: Implementations in multiple programming languages (e.g., C++, Python, Java).
- Explanations: Detailed explanations and comments for each solution to aid understanding.
- Challenges: A selection of challenging problems to push my limits and improve my skills.
- Explore: Browse through the different directories and files to find problems and their solutions.
- Run: Follow the instructions in each problem’s directory to run the code. You may need to install dependencies if required.
- Learn: Review the code and explanations to understand the problem-solving approach and algorithmic concepts.
- Contribute: If you have suggestions for improvements or additional problems, feel free to open an issue or submit a pull request.
- Arrays
- Linked Lists
- Stacks
- Queues
- Trees (Binary Trees, Binary Search Trees, AVL Trees)
- Graphs (DFS, BFS, Shortest Path Algorithms)
- Dynamic Programming
- Hashing
- Sorting and Searching Algorithms
- And more...
This repository is continually updated as I work through more problems and refine my solutions. Check out the commit history to see my progress and updates.
To get started with this repository:
- Clone the repository:
git clone https://github.com/yourusername/your-repo-name.git
