Single Linked List - All Operations
// the single linked list node class Node{ int data; Node next; Node(int x){ this.data=x; this.next=null; } } public class Main { // head and tail of linked list // we are maintaining a tail pointer too, as it helps us in inserting at the last of linked list very //easy Node head; Node tail; // function to add a new node in linked list // Time Complexity - O(1) , Space Complexity - O(1) public void addNode(int x){ // create a new node with data x, Time Complexity - O(1) , Space Complexity - O(1) Node newNode = new Node(x); // if linked list is empty if(head==null){ ...
