Create tree question

#1

what is this format of output?
2 => 1 <= END
3 => 2 <= END
END => 3 <= END

#2

@sktg99
Its a modified preorder traversal. For each node , first print its left child’s data and the data of the current node and then the data of its right child. If either the left or the right child do not exist, print END in its place. Put the arrows in between while printing.
