DE EN Français PL RU UK ZH-HANS

Le code de Huffman est un type spécifique de code de préfixe optimal qui est couramment utilisé pour la compression de données sans perte. L'algorithme a été développé par David A. Huffman alors qu'il était étudiant en doctorat au MIT et a été publié en 1952.

La sortie de l'algorithme de Huffman peut être considérée comme une table de codes de longueur variable pour le codage d'un symbole source. L'algorithme dérive cette table de la probabilité estimée ou de la fréquence d'occurrence (poids) pour chaque valeur possible du symbole source. Comme dans d'autres méthodes de codage entropique, les symboles les plus courants sont généralement représentés en utilisant moins de bits que les symboles moins courants. ...

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=py config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
