Removing duplicate elements from a sorted linked list involves eliminating nodes with repeated occurrences of similar elements while maintaining the sorted order of the list.
In order to remove duplicates, we traverse through the linked list one node at a time while checking is the next node’s value is same a current node. If the next node’s value is same as the current node’s value, we skip/delete the next node and point the current node’s reference to next next node.
