Huffman coding - Rosetta Code
WebbHuffman coding is a greedy algorithm, reducing the average access time of codes as much as possible. This method generates variable-length bit sequences called codes in such a way that the most frequently occurring character has the shortest code length. This is an optimal way to minimize the average access time of characters. Webbprogramme Python, il faut commencer par l’ouvrir par l’appel de fonction open(, []) qui retourne un objet de type file.
