WebDie Huffman-Codierung verwendet eine spezifische Methode zur Auswahl der Darstellung für jedes Symbol, was zu einem Präfixcode führt (manchmal als "präfixfreie Codes" bezeichnet, d. h. die Bitfolge, die ein bestimmtes Symbol darstellt, ist niemals ein Präfix der Bitfolge, die ein anderes repräsentiert representing Symbol). WebBibliothek konstruiert den Huffman-Code direkt aus einer Folge von Indizes, d. h. sie berechnet intern die Wahrschein-lichkeit jedes Index und verwendet sie als Grundlage für den Code.

"WebAlgorithm for creating the Huffman Tree-. Step 1 - Create a leaf node for each character and build a min heap using all the nodes (The frequency value is used to compare two nodes in min heap) Step 2- Repeat Steps 3 to 5 while heap has more than one node. Step 3 - Extract two nodes, say x and y, with minimum frequency from the heap. " - Huffman code rechner
