Web11 jan. 2024 · Principle of Huffman Encoding algorithm Huffman’s algorithm is based on the construction of a binary tree that represents the code. Let T be that binary tree. Each node in T except the root represents a bit (0 or 1) in the code. A left child is represented by a 0 and a right child is reprensented by a 1.
