The Email challenge (#21) appears to be broken again. No mail is being received. Tried with multiple mail services to no avail.

12 May - 11:47 am

Working again now.

10 May - 4:05 pm

Hello, sorry for the late answer, in fact yes there is an issue with the mail, we will try to fix it quickly. Thanks for reporting

7 May - 6:07 pm

Hi there is a issue for the challenfe Email (number 21). I don't receive a mail on any of them: gmail, hotmail, yahoo. do i fail or is it the challenge ?

28 Feb - 10:35 am

Yes we fixed it

27 Feb - 10:00 pm

Thank you, just validated contest22. The solution checker seems to have been fixed.

27 Feb - 8:40 am

Yes several solutions are accepted of course. I will check one of your answers

26 Feb - 7:51 pm

No 500 error, but the solutions I'm submitting can be verified to be correct. It can't be that only one configuration is accepted, right? - as there are multiple correct configurations for each problem.

26 Feb - 5:54 pm

contest 22 is not concerned by the issue I found, and seems to be working (I suppose you don't have 500 error on this one ?). Your solutions are indeed rejected, but I did not check them yet

26 Feb - 3:25 pm

The validation for contest 22 also seems to be wrong (it's not accepting solutions that are clearly correct). I submitted bug report yesterday.

The objective of this challenge is to analyze an image so you can count the different items of which it is composed.
The 2 images you are going to get are composed of circles, rectangles and triangles. The background is plain and the drawings have the same color. Here is an example of an image you can obtain :

In this example, there are 6 rectangles, 2 triangles, and 6 circles.
You must do this work on 2 PMG images, that you get in the variables img1 and img2. You must send back the number of rectangles in the image 1 in nb_rectangles_1, the number of triangles in this image in nb_triangles_1 and the number of circle in nb_cercles_1. The principle is the same for the image 2.
