Problem Description: You are given a sorted doubly linked list. Your task is to implement a function removeDuplicates that removes all duplicate elements from the list, leaving only distinct elements. Input: Sorted Doubly Linked List: 1 <=> 2 <=> 2 <=> 3 <=> 4 <=> 4 <=> 4 <=> 5 Output: Doubly Linked List after Removing Duplicates: 1 <=>2 <=> 3 <=> 4 <=> 5 Explanation: The provided input is a sorted doubly linked list with some duplicate elements. The removeDuplicates function is applied to remove duplicate elements, leaving only distinct values in the list. The duplicates are removed as follows: The second occurrence of 2 is removed. Two of the three occurrences of 4 is removed. The resulting doubly linked list contains only distinct values in ascending order: 1 <=> 2 <=> 3 <=> 4 <=> 5
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
