T-414-ÁFLV: A Competitive Programming Course (2016 edition)

We will be holding our course about Competitive Programming for the second time during the three weeks from April 25th to May 13th. The format will be similar as before, but hopefully with a fresh set of problems.

Note: The course material is now accessible on Github. Contributions are welcome.
