Welcome to the Data Structures and Algorithms (DSA) Practice Problems repository! This collection of practice problems is designed to help you strengthen your understanding and implementation skills of various data structures and algorithms. It serves as a valuable resource for aspiring programmers, coding enthusiasts, and anyone looking to improve their problem-solving abilities.
This repository contains a wide range of DSA practice problems that cover different topics and difficulty levels. The problems are designed to be solved using popular programming languages such as Python, Java, C++, and more. Each problem is accompanied by a clear problem statement, input/output specifications, and example test cases to guide you through the problem-solving process.
The practice problems in this repository are carefully crafted to cover a variety of concepts, including but not limited to:
- Array manipulation
- Linked lists
- Stacks and queues
- Trees and graphs
- Sorting and searching algorithms
- Dynamic programming
- Recursion
- Backtracking
- And more!
To get started with the practice problems, follow these steps:
- Clone the repository to your local machine using
git clone <repository-url>
or download it as a ZIP file. - Choose a problem you want to work on from the available categories.
- Navigate to the corresponding problem directory.
- Read the problem statement and understand the requirements.
- Implement your solution in your preferred programming language.
