There was actually a web page that would answer your stack overflow answer by running and benchmarking all of them.

There was also a plugin that would allow you to directly grab code from stack overflow and put it right into your project, kinda of like a search engine for laziness (I think it was an Atom plugin)

There's stacksort, a sorting algorithm that searches StackOverflow for sorting functions and runs them until it returns the correct answer.

An implementation is here https://gkoberger.github.io/stacksort/

Also https://github.com/drathier/stack-overflow-import which turns upvoted answers into modules.
