Kth node from the linked list

#1

How to make the fast pointer to move kth node further and perhaps a single node .can i use loop for that purpose lets say
for(int i=0;i<k;i++){
fast=fast->next;
i++;
}

or any optimal solution ?

Yes you can do like this . Moving the fast pointer k steps ahead beforehand.And then move both fast and slow pointer at the same rate.
for(int i=0;i<k;i++){
fast=fast->next;
}
Since this is a linked list, its an optimal way as any case you need to traverse all nodes.
