Hello everyone!↵
↵
I'm happy to invite you to take part in the [second edition of InfO(1) Cup](http://info1cup.com/), an online contest meant to be similar to international olympiads such as IOI, CEOI, BOI, APIO, etc. If you remember last year's entry about the contest, you should notice that we've been talking about making it an onsite event, but we decided it's both easier (especially financially) and helpful to more people (as we can have more online participants) to have it online.↵
↵
The contest consists of 2 rounds: the national round and the international round. Participation in both rounds is invitation based (you can see the "official" participants [here](http://info1cup.com/participants)). We've tried to reach out to the official organizers of Informatics Olympiad in several countries to make the competition as fierce as possible by having future IOI-participans, as well as to help those students in their training for upcoming international olympiads.↵
↵
↵
Both rounds will have online mirrors (which are the purpose of this entry), that you're all invited to take part in. Both online mirrors will be taken in the usaco format. The first round is similar in difficulty to a div2 contest, 5 problems in 4 hours, whereas the international round (the one meant to be similar to IOI, CEOI, etc) will last for 5 hours and participants will have 4 problems to solve. If you are a strong participant, then we advise you to take part in the international round and if not, both rounds should be a good training.↵
↵
The registration button for the online mirrors will become available at the beginning of the online mirrors (keep in mind that you can choose whatever 4 or 5-hour slot you want, you'll have several days to choose from for round 2, and only one for round 1). I will update the blog with the link to the registration button as soon as possible. <s>You can take the first online mirror during this [time interval](https://www.timeanddate.com/worldclock/fixedtime.html?msg=National+Round+Online+Mirror&iso=20180303T14&p1=5121&ah=20)</s> (we will keep the online mirror of round 1 after the one of round 2, and will reupdate the blog with the exact time), and the second one will start at [this time](https://www.timeanddate.com/worldclock/fixedtime.html?msg=International+Round+Online+Mirror&iso=20180304T17&p1=5121) and last for 72 hours. As in the case of all contests with this format, we kindly ask the participants not to discuss the problems until the end of both the official round and its online mirror (may it be the national or international round).↵
