You have reason, now i recheck my algorithm.

1. Resulting melds are:
   7-7-7 x1
   6-7-8 x3
   There are 3 seven so 3 differents combinations.

11-12-13
11-12-13-1
1-2-3
13-1-2-3

Thanks for the feedback man! I'll implement it right away!

Looks like there was an issue with my solution, please try again, and let me know if your answer still diverges from the given solution.

Done, thanks!

Done!

I thought I have done that, I must have a look... but now I'm largely behind my schedule so I have to wait a bit.
Thanks for your feedback and your ideas of tests.

@Absurdated: Oh! Yes, as soon as I have time I'll do that!

Edit: Done!

Glad you enjoyed it and didn't give up. :)

Finally done, I'm learning lots of things with you, I thank you so much for your patience and availability!!!

I made the drawing with "Word". I don't know how to make a "plain image":-(

Hm, since this seems like an image that could be easily vectorized, you could use Inkscape to create it. Also, you can import PDFs in Inkscape and export the image as PNG. Maybe that's possible in word too. Also, there are many online pdf->png converter, but keep in mind that they will probably use the complete page instead of only the figure.

You said "upload somewhere" but where? I thought it must be something like Dropbox or similar.

There are several sites specialized for image hosting, for examle imgur.com. Regardless of which site you actually choose, they should support direct links.

I will read your reference later but thanks!

You should know that if you are a senpai I'm a very kōhai!

I never said that you need to put it between two lines of ```. Please read the documentation for github flavored markdown and the mastering Markdown guide. Also, a PDF can't be used. You need a plain image format like JPG, PNG or GIF and a direct link to the image, not some intermediate site.

I made a drawing (I'm not a good drawer!) and I posted it. Can you have a look at this in the description. I enclosed
what you said with the url : https://app.box.com/s/7symbm3ed5z541am2c5qzzjwb90c4tkj

between two lines of ```
but it doesn't seem to work directly. You have to copy and paste the link. Maybe alternative text was not necessary, I could have put only the link(?)
