🔄 Day 36 | DSA | Circular Linked List A Circular Linked List is a variation of a linked list where: The last node points back to the first node Can be singly or doubly linked Forms a closed loop, enabling continuous traversal --- 🔍 Why Use Circular Linked Lists? ✅ Efficient in implementing circular queues ✅ Continuous traversal with no null checks ✅ Useful in applications like round-robin scheduling, multiplayer games, music playlists, etc. --- ✅ Java Code // Circular Singly Linked List Node class Node { int data; Node next; Node(int data) { this.data = data; this.next = this; // points to itself initially } } --- ✅ C Code // Circular Singly Linked List Node struct Node { int data; struct Node* next; }; // Creation struct Node* createNode(int data) { struct Node* newNode = (struct Node*)malloc(sizeof(struct Node)); newNode->data = data; newNode->next = newNode; // points to itself return newNode; } - 💡 Note: In circular singly linked lists, the next of the last node points to the head. In circular doubly linked lists, both next and prev are circularly connected. --- 📌 Follow @codewithbrains for daily DSA visualizations and explanations! --- #programming #coding #code #dsa #programmers #java #cse #datastructure #softwareengineer #algorithm #computerengineering #engineers #dev #developer #coders #softwareengineering #softwaredevelopment #backend #dsaeveryday
