WebJan 31, 2024 · Add a node at the end: (6 steps process) The new node is always added after the last node of the given Linked List. For example if the given Linked List is 5->10->15->20->25 and we add an item 30 at the end, then the Linked List becomes 5->10->15->20->25->30. Since a Linked List is typically represented by the head of it, we have to … WebFeb 22, 2024 · GFG () { this->head = nullptr; } void push (int data, Node* temp) { if (this->head == nullptr) { Node* node = new Node (data); this->head = node; node->next = this->head; return; } if (temp == nullptr) { temp = this->head; } if (temp->next == this->head) { Node* node = new Node (data); node->next = this->head; temp->next = node; return; }
