Link list append doubt

#1


sir it is working fine for test case-1 but showing run error for other test cases.Pl resolve

#2

there is no need to compute the length of the linked list.
you just need to build your list by every time insertAtTail function
and refer this part of the code
void movelast(node*&head)
{
if(head==NULL || head->next==NULL)
{
return;
}
nodesecLast=NULL;
nodelast=head;
while (last->next != NULL)
{
secLast = last;
last = last->next;
}
secLast->next=NULL;
last->next=head;
head=last;
}
void kappend(node*&head,int k)
{
int count=0;
for(int i=0;i<k;i++)
{
movelast(head);
}
}
APPROACH:move the last node to the front and second_last node should be made to point to NULL

#3

But ,why is it showing run time error in my code in test cases-2,3,4 and passing first test case

#4

And also tell,where to insert these functions in the code

#5

Pl tell where i need to make corrections in the code

#6

when you dry run your code for this input case

1 2 3 4

It will not work.
