What is this?
Want to find out what the Prologin algorithmic exercises are like? In this section, you can browse and tackle all the problems from the previous Prologin events. These are problems from both the Prologin online qualifications and the on-site regional events.
How does it work?
Read the problem statement carefully and submit your solution. The system will check your submission and instantly tell you whether you got it right or wrong. You can submit as many codes as you need to solve the problem.
If you need any help with the automatic correction system, you can read the online judge manual.
