Welcome to my Data Structures & Algorithms (DSA) Repository 👨💻
This repo documents my complete DSA learning path — implemented in both Python 🐍 and C++ ⚡ —
I’m preparing for tech rounds at product-based companies (like Zoho, Amazon, and others),
focusing on problem-solving, logic development, and code optimization.
This repository tracks my daily DSA progress, concept breakdowns, and hands-on implementations —
from Basics → Patterns → Recursion → Advanced DSA.
| Phase | Topic | Description | Status |
|---|---|---|---|
| 1️⃣ | Pattern Problems | Build logic using nested loops, symmetry, and visualization | ✅ Completed |
| 2️⃣ | Basic Maths | Learn mathematical foundations used in algorithms | ✅ Completed |
| 3️⃣ | Arrays & Hashing | Work with data storage, traversal, and frequency problems | 🔄 In Progress |
| 4️⃣ | Recursion & Backtracking | Learn problem breakdown and decision tree logic | 🔜 Upcoming |
| 5️⃣ | Sorting & Searching | Implement efficient algorithms and understand complexity | 🔜 Upcoming |
| 6️⃣ | Linked Lists & Stacks | Deep dive into pointers, memory, and dynamic data structures | 🔜 Upcoming |
| 7️⃣ | Trees, Graphs & DP | Master structured & optimized problem-solving | 🔜 Planned |
- Breaking problems into sub-parts
- Understanding time and space complexity
- Dry-running & visualizing loop patterns
- Divisors, Prime Checks, and Armstrong logic
- Logarithmic digit counting and GCD/LCM
- Efficient number manipulation using math functions
- Mastering nested loop relationships
- Pyramid, Diamond, Hollow, and Butterfly patterns
- Logic-based visualization of symmetry
I’m writing every concept in both C++ and Python to:
- Strengthen logic language-independently
- Prepare for both competitive programming and technical interviews
This entire journey is guided by
👉 Striver’s A2Z DSA Sheet (TakeUForward)
- Complete DSA roadmap — from basic to advanced
- Covers patterns, maths, arrays, recursion, graphs, DP, etc.
- Designed for placement preparation & interview success
- ✅ Strengthen logic fundamentals
- 🔄 Solve 3–5 problems daily
- 💬 Document every concept clearly
- 🧠 Build intuition for optimizing brute force
- 🏢 Crack product-based company interviews
