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

P3: Remove Duplicates from a Sorted Doubly Linked List (15 points)
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
