Find n th node from the end of a linked list
WebThen we’ll find out the index of that kth node from the beginning of the list by subtracting its position, from the end, from the length of the linked list. We can solve this problem in one traversal only. The idea is to start from the head node to move a pointer K nodes ahead in given list.
