I'm sorry, I was angry that someone posted my code on that page and
over-reacted. I apologize.

Agreed, and the page with the code may indeed be considered a valid
contribution. However, it certainly would be more valuable if it wasn't bare
code, but also included explanations of the mathematical or programmatical
ideas behind it.
The page with just the answers I cannot but find worthless.

The educational value would be more visible if the code was explained, but

I disagree, more valuable would be an explanation of the ideas behind it, and
perhaps contrasting a C (python,...) programme with a Haskell one to
highlight the different approaches.

PE has a share-alike license, the very least to be demanded if someone posts
other's code is proper attribution.
