Which one of the following codes can be used for finding a cell in the linked list which is just before what we are searching? (If the list is 1,2,3,4,5 and we search for 3, we want the algorithm to return 2.)

Select one:

a. Function(Cell: top) While (top != null) Print top.Value top = top.Next End While End Function

b. Function(Cell: top, Value: target) If (top == null) Return null While (top.Next != null) If (top.Next.Value == target) Then Return top top = top.Next End While Return null End Function

c. Function(Cell: top, Cell: a_cell) a_cell.Next = top.Next top.Next = a_cell End Function

d. Function(Cell: top, Value: target) While (top != null) If (top.Value == target) Then Return top top = top.Next End While Return null End Function
