📘 Welcome to Part 166 of Code & Debug’s DSA in Python Course! In this video, we solve the classic interview problem: Find Pairs with Given Sum in a Doubly Linked List from GeeksforGeeks. We’ll explore three different approaches, Brute Force, Better (using HashSet), and the Optimal Two-Pointer Technique, so you understand the trade-offs and can ace this problem in any coding round! 👨🏫 What’s covered in this video: 1. Problem statement explanation from GFG 2. Brute Force approach with nested loops 3. Better approach using HashSet for O(N) time 4. Optimal Two-Pointer approach for sorted DLLs 5. Step-by-step Python code walkthrough for all methods 6. Time and Space Complexity analysis for each solution By the end of this video, you’ll know how to solve pair sum problems in doubly linked lists using multiple techniques and explain your approach confidently in interviews! 🔗 GFG Problem - Find pairs with given sum in doubly linked list: https://www.geeksforgeeks.org/problems/find-pairs-with-given-sum-in-doubly-linked-list/1 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/find-pairs-with-given-sum-in-doubly-linked-list/ 📄 Full Playlist Sheet (All Questions in Order): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🎓 Enroll in the FREE Python DSA Course: https://codeanddebug.in/course/master-dsa-with-leetcode 🚀 Advance Python DSA for FAANG (Zero to Hero Course): https://codeanddebug.in/course/zero-to-hero-python-dsa Stay focused and keep coding with Code & Debug.
