LeetCode Solutions in Java
This repository is a comprehensive collection of LeetCode problems solved in Java. It is designed for students, developers, and anyone preparing for coding interviews. Each solution focuses on clarity, efficiency, and correctness, providing insights into algorithmic problem-solving.
The repository includes solutions for problems across multiple categories, such as Arrays, Strings, Linked Lists, Trees, Graphs, Dynamic Programming, and more. Each problem solution is accompanied by a brief explanation of the approach and time & space complexity analysis.
The goal is to create a reference library for Java programmers who want to:
Practice algorithm and data structure problems.
Learn clean coding practices in Java.
Understand different problem-solving techniques.
Prepare effectively for technical interviews.
Each Java file in the repository is well-structured and documented, so you can understand the logic without having prior knowledge of the problem. The solutions are optimized for performance while keeping the code readable and maintainable.
The repository is organized by problem categories for easy navigation. For example:
Array: Common array problems like Two Sum, Maximum Subarray, etc.
LinkedList: Reverse, merge, and manipulate linked lists.
Tree & Graph: Traversals, searches, and other tree/graph algorithms.
Dynamic Programming: Classic DP problems to practice optimization techniques.
Whether you are a beginner or an experienced programmer, this repository is a great resource to enhance your Java skills and improve your algorithmic thinking.
It also encourages contributions. You can submit new solutions, optimizations, or problem categories, making this repository a living and evolving resource for the programming community.
This project is suitable for anyone who wants to learn, practice, or reference Java solutions for LeetCode problems efficiently. By exploring this repository, you can gain a deep understanding of algorithms, data structures, and problem-solving strategies.
