Remove duplicates from a sorted doubly linked list

A doubly linked list is a data structure consisting of a sequence of nodes, where each node contains a value and pointers to both the previous and next nodes in the sequence. In a sorted doubly linked list, the nodes are arranged in order based on the value they contain.

Removing duplicates from a sorted doubly linked list means removing any nodes in the list that have the same value as a previous node in the list.

Suppose we are inserted the following ( 5, 5, 7, 9, 9, 11, 45, 45) node in a sequence.

To remove duplicates from a sorted doubly linked list, you can iterate through the list and compare the value of each node with the value of the previous node. If the values are the same, you can remove the current node by updating the pointers of the previous and next nodes to skip over it.
