🚀 LeetCode DSA Solutions

Welcome to my LeetCode DSA repository! 👋

image

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.
