In order to delete the last node of the singly linked list do this;
1.Take two pointers.
2.Assign 1st pointer to the head and 2nd to the next node.
3.traverse the list till the last node such that 2nd ptr points to last node and 1st ptr oints to the previous node.
4.assign NULL to the 1st ptr .
5.Free the 2nd ptr
