How should I implement this function with a Doubly Linked List on C++. Note: Doubly Linked Lists use a prev pointer to the previous ListNode and a next pointer to the next ListNode.

Attached below is also my current code for this function.

The functionality of my code is as follows:

current List:

<1 2 3 4 5 6>

<2 3 1 4>

Expected:

<2 3 1 5 6 4>

Please help be debug this problem/code.
