O(N) Space to O(1) Space : Optimizing LeetCode 2130

O(N) Space to O(1) Space : Optimizing LeetCode 2130 Welcome back to AeXeL . In this video, we tackle LeetCode 2130: "Maximum Twin Sum of a Linked List." As campus placements get closer, mastering linked list manipulations like finding the middle and reversing nodes is an absolute must for coding rounds. I'll walk you through two approaches in C++: 1️⃣ The Brute Force approach using a vector (O(N) Time, O(N) Space) 2️⃣ The Optimal approach using the Fast/Slow pointer technique and reversing the second half of the list to achieve O(1) Space! 📌 What you will learn in this video: Understanding the "twin sum" logic in a linked list. Storing linked list values in an array/vector (Brute Force). Finding the middle of a linked list. Reversing a linked list in-place (Optimal). Comparing Time and Space Complexities. #LeetCode #LeetCode2130 #CPP #CompetitiveProgramming #LinkedList #DataStructures #Algorithms #PlacementPrep #CodingInterview #SoftwareEngineering #aexel
