WebHuffman Codes are Optimal Lemma: Consider the two letters, x and y with the smallest fre-quencies. Then is an optimal code tree in which these two letters are sibling leaves in the tree in the lowest level. Proof: Let T be an optimum preﬁx code tree, and let b and c be two siblings at the maximum depth of the tree (must exist because T is full). Web1 day ago · This is repeated for all characters and binary codes. The Huffman tree is thus recreated in this manner.->The remaining file is now read bit by bit, and the corresponding 0/1 bit in the tree is traversed. The corresponding character is written into the decompressed file as soon as a leaf node is encountered in the tree.
