Question

C++

Use the following struct definition in your program:
struct node
{
int data;
struct node* next;

node(int x){
data = x;
next = NULL;
}

}*head;

Given a linked list of size n. The task is to reverse every k nodes (where k is an input) in the linked list and print them out.

Expected Time Complexity – O(N)
Expected Auxiliary Space – O(1)

Example Input & Output:
Enter n:
8
Enter k:
4
Enter elements of a linked list (non-negative numbers):
1 2 3 4 5 6 7 8
Output:
4 3 2 1 8 7 6 5
