Do they? I very much doubt that.

I can't tell you how many times I've caught juniors trying to pass off unmodified SO answers as their own work. It's rather alarming to me because they have this attitude that popular things can't be wrong, and public things don't need attribution. But knowing, that people often approach life in this way, is half the battle.

Could be worse when I’m really tired I copy the code from the question and fix that.

Can someone explain why is this special? It doesn't look anything more than an algorithm implementation

I was curious too, so I have ran the included benchmark for a 500x500 matrix and my naive Kotlin A* implementation runs faster on the same input. So what are we missing here?

Lesser known is that SO content is generally under a CC-BY-SA license, which means not only attribution, but also "share-alike", which generally means releasing derivative work under the same license...

There is significant legal risk if your juniors are pasting non-trivial code from SO into your codebase verbatim...
