Salut nikokks Ce problème n'est pas évident en effet. Une manière de faire est de trouver les formes les plus simples, et de les "effacer" de l'image avant de chercher les formes plus complexes ;)

Salut a tous =) , je bug sur le problème 28 (forme analysis). Quelqu'un aurait il une piste ?

29 Sep - 5:38 pm

Coucou oui, tu peux m'envoyer un mail si tu veux. Le plus simple, ce serait d'avoir un package pour python 3. J'ai essayé et ça n'a pas marché!

Salut thefinder, ça faisait longtemps ! Oula ça en fait des problèmes :'( Le premier challenge ? La somme de deux nombres ?

23 Jul - 2:13 am

Coucou, j'ai essayé de reprendre avec python. J'ai plusieurs soucis. 1) Il faut rajouter headers={'Content-Type': 'application/x-www-form-urlencoded'} avec un requests.session(). 2) Je n'ai pas réponse du serveur si je soumet une réponse au premier challenge. J'essaye finir en python les 3 dernières épreuves qui me reste. :)

Bonjour, un léger problème sur l'épreuve 10 : Une fois réussie, le champ "points earned" indique 72 au lieu de 7 En revanche sur le site le nombre de points comptabilisés est bien 7 Merci pour ce site génial !

Équation du challenge 52 corrigée, merci

16 Oct - 8:43 am

Bonjour, il y a aussi un problème d'affichage "invalid equation" dans le challenge 52. Merci

The µContest libraries

General information

To begin, I think it's interessant for those who are not familiar, to give the definition of a library (Wikipedia) :

In computer science, a library is a collection of implementations of behavior, written in terms of a language, that has a well-defined interface by which the behavior is invoked. The value of a library is the reuse of the behavior. When a program invokes a library, it gains the behavior implemented inside that library without having to implement that behavior itself.
So the µContest libraries are libraries we developped to avoid to recode the functions of connexion to the website every time. Moreover, this has the advantage to not take care of this aspect of the programmation, which is not part of the challenge.
The libraries are available in C/C++, Java and Python, and can be downloaded on the page Downloads.

libmicrocontest in C/C++

This is the second version of the lib C/C++ (it uses the version 2 of the interface).
A lot of improvements have been developped. The main good news is that the lib consists in one header file (.h). That's all.
All the code is written in the header file. This presents the huge advantage to be compatible with Debug/Release settings, with 32/64 bits, with C/C++, with every compiler/IDE, and the lib works on Windows, Linux, and MacOS. This will make the use much much simpler. And bonus, you can see the source code !

So you just have to download the file microcontest2.h, and include it in your C or C++ file with :

				#include "microcontest2.h"

You can take a look at the documentation, but it's quite simple to use and all you have to know is given in the example section.

Attention, for the users of Code::Blocks under Windows, an additional (simple) setting has to be set in the project options.
Everything is explained on this page.

libmicrocontest in Python

This is the second version of the lib Python (it uses the version 2 of the interface).
For the moment, it's only compatible with Python 2.7. But you can easily adapt its code to 3.3, and if you do it, feel free to give us this version to make it available on the website.

So you just have to download the module libmicrocontest2_python27.py, and simply import it in your Python code :

				from libmicrocontest2_python27 import *

You can take a look at the documentation, but it's quite simple to use and all you have to know is given in the example section.

libmicrocontest in Java

This is the second version of the lib Java (it uses the version 2 of the interface).
It consists in a JAR archive you must include in the build path of your project :

Once the settings of your project are rights, you just have to add theses lines at the top of your .java file :
import com.microcontest.Libmicrocontest2;
import com.microcontest.Contest;

You can take a look at the documentation, but it's quite simple to use and all you have to know is given in the example section.

libmicrocontest in PHP

This is the second version of the lib PHP (it uses the version 2 of the interface).

You just have to download the file libmicrocontest2.php_, remove the '_' at the end, and simply include it in your PHP code :

				require 'libmicrocontest2.php';

You can take a look at the documentation, but it's quite simple to use and all you have to know is given in the example section.
