Intersection of Two Linked Lists | Length Difference & Two Pointer Approach | Python Java C++

In this video, we'll solve the classic Intersection of Two Linked Lists problem using two optimized approaches. We'll learn how to find the node where two linked lists intersect by reference and understand the intuition behind both solutions. 🔹 Understand Linked List Intersection 🔹 Length Difference Approach Explained 🔹 Align Both Lists Using Length Difference 🔹 Optimal Two Pointer (m+n Traversal) Approach 🔹 Dry Run with Examples 🔹 Edge Cases and Interview Tips 🔹 Time & Space Complexity Analysis The Two Pointer approach is one of the most elegant Linked List techniques asked frequently in coding interviews and helps build strong problem-solving intuition. Complexity Analysis: ✅ Length Difference Approach • Time Complexity: O(m + n) • Space Complexity: O(1) ✅ Two Pointer (m+n Traversal) Approach • Time Complexity: O(m + n) • Space Complexity: O(1) Rising Brain (DSA Sheet): https://www.risingbrain.org/sheet Connect with me here: LinkedIn –   / anjalikumari22   Instagram –   / rbanjali.codes   Twitter (X) – https://x.com/anjali1kumari?s=21
