This repository contains my solutions and implementations of Data Structures and Algorithms (DSA), written purely in Python.
The goal is to master algorithmic thinking, optimize code efficiency, and prepare for technical interviews.
- Data Structures: Arrays, Linked Lists, Stacks, Queues, Hash Maps, Trees (BST, AVL), Graphs, Heaps.
- Algorithms: Sorting (Merge, Quick, Heap), Searching (Binary Search), Recursion, Dynamic Programming, Greedy Algorithms.
- Problem Solving: Solutions to problems from LeetCode, HackerRank, and GeeksforGeeks.
To build a strong foundation in computer science fundamentals and write clean, efficient, and well-documented Python code.
