(Use the structure below as your starting point for each question.) Head 23 35 59 - 720 Determine what the execution of the given code fragment would do to the given structure. Draw the list structure after execution of each code. a. p.next = q; b. q.next = p.next; p.next = null; c. q.next = p.next; q.next.next = p; p.next = null; d. q.next = null; delete p; e. delete (p.next); f. q.next = Head; delete p
