Sort the doubly linked list using insertion sort technique.
Initial doubly linked list
Doubly Linked List after applying insertion sort
Below is a simple insertion sort algorithm for doubly linked list.
1) Create an empty sorted (or result) doubly linked list.
2) Traverse the given doubly linked list, do following for every node.
……a) Insert current node in sorted way in sorted(or result) doubly linked list.
3) Change head of given linked list to head of sorted (or result) list.
The main step is (2.a) which has been covered in below post.
