🛣️ My Ultimate DSA Roadmap – From Basics to Internships

🛣️ My Ultimate DSA Roadmap – From Basics to Internships

Whether you're just starting out or stuck in the middle, this guide will help you navigate through Data Structures & Algorithms (DSA) with the right resources, structured planning, and consistent effort.

🔥 DSA Roadmap – Level by Level✅ Level 1: Arrays & Strings

Your DSA journey starts here. Master basic manipulations, traversals, and common question patterns.

📘 Resources:

• Love Babbar 450 DSA Sheet
• Love Babbar Playlist (YouTube)

✅ Level 2: Linked List, Stack, Queue

Dive into linear data structures and pointer-based problems. Strengthen your logic for implementation-heavy questions.

📘 Resource:

• Love Babbar Playlist

✅ Level 3: Binary Search & Sorting

Understand binary search techniques on arrays and matrices. Explore classic and advanced sorting methods.

📘 Resources:

• Binary Search – Aditya Verma (YouTube)
• Sorting – Abdul Bari (YouTube)

✅ Level 4: Recursion, Trees, Graphs, Tries, Heap

Master recursion fundamentals, tree traversals, graph traversal techniques (BFS/DFS), tries, and heaps.

📘 Resource:

• Striver’s takeUforward Playlist

✅ Level 5: Dynamic Programming, Greedy, Backtracking, Bit Manipulation

Explore higher-level concepts that often appear in interviews and contests.

📘 Resources:

• DP – Aditya Verma
• Striver’s Full DSA Playlist

❓ What If You Get Stuck?

Never copy-paste. Use this method instead:

1. Try solving the problem yourself for 30 minutes.
2. Look for hints or editorial solutions (Leetcode Discuss, GFG, YouTube).
3. Watch a video explanation only after genuinely attempting.
4. Re-attempt the problem from scratch.

✅ This “Struggle – Learn – Implement” method builds actual understanding, not just memory.

💭 Final Thoughts

✅ Don’t chase numbers.

✅ Chase patterns.

✅ Chase confidence.

Learning DSA changed my career trajectory.

I cracked interviews at Samsung R&D, interned at Hyperverge, and secured a PPO from BNY.

If I could do it from scratch—you definitely can too. 🙌
