🚀 LeetCode DSA Solutions

Welcome to my LeetCode DSA repository! 👋

This repository contains my solutions to Data Structures and Algorithms problems solved on LeetCode. The primary goal of this repository is to strengthen problem-solving skills, improve coding efficiency, and prepare for technical interviews at top tech companies.

🎯 Objectives

• Solve LeetCode problems consistently.
• Master Data Structures and Algorithms.
• Improve coding and optimization skills.
• Build strong interview preparation foundations.
• Track my learning journey and progress.

📚 Topics Covered

• Arrays
• Strings
• Linked Lists
• Stacks & Queues
• Trees & Binary Trees
• Binary Search Trees
• Heaps & Priority Queues
• Hashing
• Recursion & Backtracking
• Dynamic Programming
• Greedy Algorithms
• Graphs
• Tries
• Sliding Window
• Two Pointers
• Bit Manipulation

💻 Languages

Currently solving problems in:

• C++
• Python (Occasionally)

📈 Progress

I believe that consistency beats intensity.

One problem a day is better than solving 100 problems once and giving up.

This repository serves as a record of my growth as a programmer and problem solver.
