WebMay 8, 2024 · A doubly-linked list has symmetry; forward and backward look the same, modulo some naming differences. Putting a sentinel node after the last node breaks this symmetry, unless you also put a sentinel node before the first node. So let's put another sentinel node before the first node. But hold on – why do we need two sentinel nodes? WebFeb 26, 2014 · For a circular doubly linked list, you can setup 1 sentinel node where both "next" and "prev" points to itself when list is empty. When list is not empty, sentinel->next points to first element and sentinel->prev points to last element. With this knowledge, your insert and remove function would look something like this.

Answer: Yes. It is a more complex data structure. In a circular doubly linked list, the previous pointer of the first node contains the address of the last node and the next pointer of the last node contains the address of the first node.
