Welcome to my DSA Journey repository! 🎉 This repository is a reflection of my consistent hard work, dedication, and passion for mastering Data Structures and Algorithms (DSA). Between July 5, 2024, and December 31, 2024, I committed myself to an intensive journey of learning and problem-solving based on Love Babbar's 149 DSA videos in C++.
While this marks a significant milestone in my DSA journey, I believe that DSA is an ever-evolving field where true mastery comes from continuous learning and practice. It’s all about understanding the key aspects of each data structure and algorithm, along with their real-world applications. I am not a master yet, but I am fully committed to staying on this path and striving to improve. Who knows? I wouldn’t mind becoming a master someday! 😉
Throughout this journey, I solved numerous problems, developed a deep understanding of core concepts, and applied my knowledge extensively on platforms like LeetCode and VS Code. After completing this phase of structured learning, I continued to challenge myself and further enhance my problem-solving skills by actively participating on CodeForces, CodeChef, and GeeksForGeeks.
This repository includes organized folders for various DSA topics. Here are the topics I covered in detail:
- Sorting Techniques: Bubble Sort, Merge Sort, Quick Sort, and more.
- Searching: Binary Search, Linear Search, and advanced techniques.
- Arrays: Manipulation, optimization problems, and more.
- Strings: Pattern matching, permutations, and problem-solving.
- Backtracking: N-Queens, Sudoku Solver, and more.
- Linked Lists: Single, Double, Circular, and operations.
- Pointers & Functions: Deep dives and practical implementations.
- OOPS Concepts: Encapsulation, Inheritance, Polymorphism, Abstraction and practical implementation.
- Recursion: Fundamentals, optimizations, and real-world problems.
- Dynamic Programming (DP): Knapsack, LCS, and beyond.
- Trees & Graphs: Traversals, MSTs, Shortest Paths, and advanced problems.
- Heaps: Min/Max heaps, priority queues.
- Tries: Prefix trees, auto-complete, and applications.
- Hashing: Hash maps, sets, and collision handling. And many more...
The repository is structured topic-wise to help navigate easily. Each folder may have fewer codes compared to the problems I actually solved because a significant portion of my work is reflected in my Coding Profiles.
- Solved numerous problems on LeetCode, CodeForces, CodeChef & GeeksForGeeks.
- Implemented solutions in C++.
- Worked on all foundational and advanced DSA concepts.
- Stayed consistent and dedicated throughout this journey.
- Completed a 1-month C++ Programming Internship at CodeAlpha in May 2025, building 4 structured C++ projects like a Banking System, CGPA Calculator, Sudoku Solver, and a modular Login System.

This repository is not just a collection of codes; it’s a testament to my perseverance, consistency, and learning journey. While some folders may seem less populated, rest assured, I have given my best effort to every topic. Most of the practice reflects my extensive problem-solving on LeetCode.
I'm always open to meaningful discussions around Data Structures, Algorithms, or anything tech!
