DSA Revision – Java

A structured repository for revising and practicing Data Structures & Algorithms in Java for software engineering interviews.

The focus is on rebuilding problem-solving ability, recognizing patterns, and writing clean, efficient solutions rather than simply completing a problem list.

🎯 Goals

• Strengthen DSA fundamentals through revision
• Improve problem-solving and pattern recognition
• Practice interview-oriented problems in Java
• Revisit previously solved problems to improve recall
• Maintain consistent coding practice

📚 Topics

• Arrays
• Linked List
• Stack & Queue
• Binary Search
• Trees
• Graphs
• Dynamic Programming

More topics will be added as the revision progresses.

🧩 Approach

For each problem:

1. Attempt the problem independently
2. Identify the underlying pattern
3. Implement the solution in Java
4. Analyze time and space complexity
5. Revisit difficult or forgotten problems

Problems are organized progressively by topic and difficulty.
