The time complexity of adding an element to the end of a doubly linked list depends on whether the list has a pointer to the last element (tail).

• If there is a pointer to the tail, adding an element to the end occurs in O(1) time, as you can directly access the last element and add the new one after it.

• If there is no pointer to the tail, you need to traverse the entire list from the head to the last element, which takes O(n) time, where n is the number of elements in the list.

In most implementations of doubly linked lists, to optimize the operations of adding to the end, a pointer to the tail is maintained, so the operation is generally considered O(1).
