Sample input 2: insertEnd "now is the time" insertEnd "for all good men" insertEnd "to come to the aid of their country" print edit 2 "for all good people" print quit Sample output 2: 1 now is the time 2 for all good men 3 to come to the aid of their country 1 now is the time 2 for all good people 3 to come to the aid of their country Sample input 3 insertEnd "now is the time" insertEnd "for all good people" insertEnd "to come to the aid of their country" delete 2 print insert 2 "for all good people" print quit Sample output 3: 1 now is the time 2 to come to the aid of their country 1 now is the time 2 for all good people 3 to come to the aid of their country Implement a line editor using linked lists.
