Is this a discovery!? I'm 100% sure I wrote when I first started programming and obsessively tried to get the shortest solutions on codewars.

Did someone refer to it as a discovery? In fact, from the introduction in the article.

> It is difficult to imagine that this algorithm was not discovered before, but we are unable to find any references to it.

I expect it's "commonly rediscovered because it's so simple; rarely published because it's so obviously bad".
