A site for online training in programming and automatic task checking?

Question

IT education

I remember seeing an ad on YouTube about 2 months ago. There was a site where you could learn programming. There was also such a topic: there are tasks, you write a solution right there, and he immediately checks whether you wrote correctly. If true, then your level rises, etc. task. I remember he was black on the interface, I don’t know, maybe they changed something now. It also seemed like it was possible to write in different languages ​​​​(there were several windows for entering code).

In general, I just can’t remember what kind of site, from everything that I found in the search - it seems not right. Does anyone know what it looks like?
