Mastering Linked List Made Simple: Your Easy Guide to Data Structures !
Deletion from End in Singly Linked List Code [C++] :
#include<iostream>using namespace std;class Node{public:int data;Node* next;//ConstructorNode(int data){this->data = data;this->next = NULL;}};void delFromEnd(Node* &head, Node* &tail){// Step 1: EMpty listif(head == NULL){cout<<"List is empty"<<endl;return;}// Step 2: Non-empty listNode* temp = head;while(temp->next != tail){temp = temp->next;}tail = temp;temp->next = NULL;}void insertAtBeginning(Node* &head,Node* &tail, int data){// Creation of new NodeNode* newNode = new Node(data);// CHeck if the list is emptyif(head == NULL){head = newNode;tail = newNode;return;}newNode->next = head;head = newNode;}void print(Node* head, Node* tail){Node* temp = head;while(temp != NULL){cout<<temp->data<<" ";temp = temp->next;}cout<<endl;cout<<"Head : "<<head->data<<endl;cout<<"Tail : "<<tail->data<<endl;}int main(){Node* head = NULL;Node* tail = NULL;insertAtBeginning(head,tail,10);insertAtBeginning(head,tail,20);insertAtBeginning(head,tail,30);insertAtBeginning(head,tail,40);delFromEnd(head,tail);print(head,tail);return 0;}
