All the solutions I can find will need to use the special character to
represent the empty node. Is there a way to do it without using it?
For example:
a
b c
Will need 4 special character to represent the 4 null children nodes, which
will take too much space. Is there a way to save / load this binary tree
without using the special character?
(note: we are talking about a regular binary tree. It may not be balanced,
it is not a BST.)
