Given a linked list and an integer M, the task is to append the last M nodes of the linked list to the front.
Input: List = 4 -> 5 -> 6 -> 1 -> 2 -> 3 -> NULL, M = 3
Output: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> NULL
Input: List = 8 -> 7 -> 0 -> 4 -> 1 -> NULL, M = 2
Output: 4 -> 1 -> 8 -> 7 -> 0 -> NULL
Approach: Find the first node of the last M nodes in the list, this node will be the new head node so make the next pointer of the previous node as NULL and point the last node of the original list to the head of the original list. Finally, print the updated list.
Below is the implementation of the above approach:
1 -> 2 -> 3 -> 4 -> 5 -> 6 -> NULL
