Given a doubly linked list containing N nodes, the task is to delete all the even nodes from the list.
Input: Initial List = 15 <=> 16 <=> 6 <=> 7 <=> 17
Output: Final List = 15 <=> 7 <=> 17
Input: Initial List = 5 <=> 3 <=> 6 <=> 8 <=> 4 <=> 1 <=> 2 <=> 9
Output: Final List = 5 <=> 3 <=> 1 <=> 9
The idea is to traverse the nodes of the doubly linked list one by one and get the pointer of the nodes having data even. Delete those nodes by following the approach used in this post.
Below is the implementation of above idea:
Original List: 15 16 7 6 17 Modified List: 15 7 17
Time Complexity: O(N), where N is the total number of nodes.
