DLL Operation: Append

Suppose we have the following DLL, and we want to append (add to the end) a new node.

Exercise Complete the implementation of the addLast method that creates a node and add it to the back of the list.

public void addLast(T data) {
  // TODO Implement me!
}

Hint: Use the following visualization as guidance.

public void addLast(T data) {
  Node<T> node = new Node<>(data);
  node.prev = tail;
  tail.next = node;
  tail = node;
}
