DataStructure_And_Algorithms

A dedicated repository for my learning and problem-solving journey in Data Structures and Algorithms (DSA). This repo includes curated solutions from LeetCode, HackerRank, and GeeksforGeeks (GFG), organized by platform and problem type.


📌 Platforms Covered

  • LeetCode – Interview-level DSA questions across topics
  • HackerRank – Logic-based and language-specific practice
  • GFG – Conceptual problems and theory-based practice

📁 Folder Structure

DataStructure_And_Algorithms/ │ ├── LeetCode/ # Solutions from LeetCode ├── HackerRank/ # Solutions from HackerRank ├── GFG/ # Solutions from GeeksforGeeks


🧠 Topics Covered

  • Arrays & Strings
  • Hashing & Frequency
  • Recursion & Backtracking
  • Linked Lists, Trees, Graphs
  • Stacks & Queues
  • Sliding Window, Two Pointers, Binary Search
  • Sorting & Greedy Algorithms
  • Dynamic Programming

🎯 Goal

  • Improve problem-solving and time complexity thinking
  • Prepare for coding interviews and competitive exams
  • Build a solid DSA foundation for software and data roles

🛠 Tools Used

  • Python (Primarily)
  • Jupyter Notebooks (for explanations)
  • Git for version control

📚 Future Plans

  • Add notes and patterns folder (two pointers, sliding window, etc.)
  • Tag each problem with its difficulty and topic
  • Weekly problem updates
