Data Structure - Linked List Implementation of the 4 types of LL's in C++ - Singly Linked List Doubly Linked List Circular Singly Linked List Circular Doubly Linked List To be able to use these functions, create a main file in the outer directory. To include singly linked node and functions of SLL and CSLL, #include "header/singlyNode.h" To include doubly linked node and functions of DLL and CDLL, #include "header/doublyNode.h" The functions are: - display() - insertAtFront() - insertAtEnd() - insertAtPosition() - deleteFromFront() - deleteFromEnd() - deleteFromPosition() To be able to call the requred functions, use respective namespaces: Linked List Namespace Singly Linked List SLL Doubly Linked List DLL Circular Singly Linked List CSLL Circular Doubly Linked List CDLL
