Lecture -05 Basic Definition of Linked List and Pointers.

Arrays are great — but what if you need dynamic memory? 🤔 Say hello to the Linked List — one of the most important data structures in programming! In this video, we start from absolute zero and build a complete understanding of what a Linked List is and how Pointers make it all work. 🧠💡 📌 What You'll Learn: ✅ What is a Linked List? (Simple Definition) ✅ What is a Node? (Data + Pointer) ✅ What are Pointers & how do they work? ✅ How nodes are connected using Next Pointer ✅ What is the HEAD node? ✅ What does NULL mean at the end? ✅ Linked List vs Array — Key Differences ✅ How memory is allocated dynamically 🔍 Node Structure (Quick Reference): struct Node { int data; ← stores the value Node* next; ← stores address of next node }; 📊 Array vs Linked List: FeatureArrayLinked ListMemoryContiguousDynamicSizeFixedFlexibleAccessO(1)O(n)Insert/DeleteO(n)O(1) 🔥 Full DSA Playlist: https://youtube.com/playlist?list=PLa42z3dBCS-au-DzjKq1T-CQF-h5PuYxz&si=yzieEBh44Lsk2YPm 💬 Never understood pointers?
