🧠 LeetCode Solutions

Welcome to my LeetCode practice/problem-solving repository!

This repository contains my solutions to LeetCode problems as I work on strengthening my Data Structures & Algorithms skills, improving problem-solving ability, and preparing for technical interviews.

🎯 Goals

• Strengthen Data Structures & Algorithms fundamentals
• Develop efficient problem-solving approaches
• Improve logical and analytical thinking
• Practice writing clean and optimized code
• Build consistency in coding practice
• Prepare for technical interviews and coding assessments

💻 Language

• Java

📚 Topics

My practice covers a variety of Data Structures & Algorithms concepts, including:

• Arrays
• Strings
• Hash Tables
• Linked Lists
• Stacks & Queues
• Trees & Graphs
• Recursion & Backtracking
• Sorting & Searching
• Dynamic Programming
• Greedy Algorithms
• And more as I continue learning

🚀 My Approach

For each problem, I aim to:

1. Understand the problem and constraints
2. Identify an appropriate approach
3. Analyze time and space complexity
4. Implement a clean solution
5. Learn from alternative and optimized approaches

📈 Continuous Practice

This repository is a record of my ongoing journey with Data Structures & Algorithms.

I believe consistent practice, understanding the reasoning behind a solution, and learning from mistakes are more valuable than simply counting solved problems.
