    def insert(self,head,data): temp = Node(data) if head is None: head = temp return head current = head while current.next is not None: current = current.next current.next = temp return head
    Problem solution in java programming. public static Node insert(Node head,int data){ // if list has no elements, return a new node if(head == null){ return new Node(data); }

        // else iterate through list, add node to tail, and return head
    Node tmp = head;
    while(tmp.next != null){
        tmp = tmp.next;
    }
    tmp.next = new Node(data);

    return head;
}
