WebApr 17, 2009 · You do, however, need the actual tree. So for each node, starting at root: If leaf-node: Output 1-bit + N-bit character/byte If not leaf-node, output 0-bit. Then encode both child nodes (left first then right) the same way To read, do this: Read bit. If 1, then read N-bit character/byte, return new node around it with no children WebFeb 27, 2013 · Building Huffman Trees is very cheap computationally, so there's little point in storing in a special format.
