I wanted to do some data analysis on source code: I wanted to build a model which determines the language of a source code snippet. Codeforces seemed like a perfect data source for this: each submission has source code and it's tagged with the programming language.

So I scraped the data from codeforces and here I want to share it for people who also might want to have it. I store the following columns:

• submission_id — the ID of the individual submission
• source — the source code of the submission
• status — the verdict of the submission (accepted, not accepted, compilation error, etc)
• language — the programming language which was used to make the submission
• problem — the ID of the problem

I scraped about 270k submissions, mostly C/C++.

It's a MySQL dump, so you'll need MySQL to use it.

You can read more about it here: http://www.itshared.org/2015/12/codeforces-submissions-dataset-for.html

Please let me know if this is against the rules to share such a dataset and I'll remove it.
