    Python 3 Solution; def insert(self,head,data): new_node = Node(data) if head is None: head = new_node else: current = head while current.next: current = current.next current.next = new_node return head

    Simple JAVA approach

    public static Node insert(Node head,int data) {

        if(head==null){
        head = new Node(data);
    }
    else{
        Node start = head;
        while(start.next != null){
        start = start.next;
    }

    Node newNode = new Node(data);
    start.next = newNode;
    }
    return head;
}

    I was hoping for a golang option. C++ is good enough I suppose...

    Node* insert(Node *head,int data)
      {
          //Complete this method          
          Node *dummyNode = new Node(0);
          dummyNode->next = head;
          Node *newNode = new Node(data);
          Node *current = dummyNode;
          
          while (current->next != NULL) {
            current = current->next;
          }
          current->next = newNode;
          return dummyNode->next;
      }

    public static  Node insert(Node head,int data)
	{
      
    Node newNode = new Node(data);
  
    if (head == null)
    {
        return newNode;
    }

    Node current = head;
    while (current.next != null)
    {
        current = current.next;
    }

    current.next = newNode;
     return head;
    }
