In a doubly linked list the first class is Node which we can create a new node with a given element. Its constructor also includes previous node reference prev and next node reference next. make a node object for the new element. Check if the index >= 0. If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index. If the previous node is not null, adjust the prev and next references. Print a message when the previous node is null.   implement these 3 methods: insert_at_index(), delete_at_end(), display(). use these three functions above use this to name the items

In a doubly linked list the first class is Node which we can create a new node with a given element. Its constructor also includes previous node reference prev and next node reference next.

make a node object for the new element. Check if the index >= 0.
If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index.
If the previous node is not null, adjust the prev and next references. Print a message when the previous node is null.

implement these 3 methods: insert_at_index(), delete_at_end(), display(). use these three functions above

use this to name the items

1. insert_to_empty_list()
2. insert_to_end()
3. insert_at_index()

4. delete_at_start()

5. delete_at_end() .

6. display()

let the output be
