After the while loop "sp" would be containing the address of the node 
after
 which the new node is to be inserted.
 
 It is done in this way because *sp = *sp->next would modify the global
 "empty" pointer which we dont want. "empty" should always point to
 first element of the list.  
 
 Hope this helps.
