Web4 apr. 2024 · We can recreate the Huffman tree using this. For each binary code: A left edge is created for 0, and a right edge is created for 1. Finally, a leaf node is formed and the character is stored within it. This is repeated for all characters and binary codes. The Huffman tree is thus recreated in this manner.
