Simple C Program to get the kth node from last in a linked list

This can be done in single traversal using two pointers . First move to the kth node from first and point it using temp pointer . Point the head node using another pointer called kthnodefromlast .Now Move the temp pointer and kthnodefromlast to next node till temp node reaches the end of the linked list.

Example:

 1->2->3->4->5->6->7->NULL

 For the above linked list kth(k=3) node from last is 5.

 Code:(in C)
Time Complexity : O(n)
Space Complexity: O(1)
