  1. Study the following method carefully which can be related to a certain class, decide what does it do?

        public void Unknown(E item)

        {

            Node<E> node = new Node<E>(item);

            Node<E> parent=null, current;

            char d;

            if(root == null)

                root = node;

            else

             {

                current = root;

                while(current != null)

                 {

                      parent = current;

                      if (current.data < item)

                            { current = current.right;

                               d=’r’; }

                       else

                           {   current = current.left;

                                d=’l’;

                            }

                   }

                  if(d==’l’)

                   parent.left = node;

                 else

                 parent.right = node;

             }

        }

     

     

     

     

     

     

     

     

     

      a.

    Remove a node which its data is equal to item from a binary tree

     

      b.

    Remove a node which its data is equal to item from a binary search tree

      c.
