I'm looking for a dataset of solved programming challenges, like the ones on http://codeeval.com. The dataset should have the natural language description of the problem and N solutions for each problem, possibly in different programming languages.
An API for extracting this kind of data from some programming challenges site would fit too.
You'd have to piece it together, but Project Euler has many solutions to the same problems hosted on github
https://github.com/topics/project-euler
You can get the text of the problems with the URL
https://projecteuler.net/problem=719
and also some machine readable info from the questions: https://projecteuler.chat/viewtopic.php?t=3003
