{
if(start NULL)
return;
printf("%d ", start->data);
if(start->next != NULL)
fun(start->next->next);
printf("%d", start->data);
}​

Answer 2

The output of the function is 135531

Explanation:

void fun(struct node* start)

{

if(start NULL)

return;

printf("%d ", start->data);

if(start->next != NULL)

fun(start->next->next);

printf("%d", start->data);

}​

• the output of the following function for given linked list 1→2→3→4→5→6 with a starting point to the first Node of linked list is 135531
• hence, the output of the following function is 135531
