      At first even the leaders had not any way to know the contestants' submission so I guess this is better

In this ejoi there are a lot of problems. Why? This is a big organization.

CEOI in Slovenia also had many problems. Most importantly, tasks were all like Div2 D (maybe E) on Codeforces, it was a speed-typing contest.

    I bet it was — this EJOI is also awfully organized, we (the leaders) are getting no information on what the hell is happening with the competition (there were some rejudgings, changes, etc..)

      Public announcement (which was everything but not public): Results on problem tower are not valid and they are being calculated by hand, will be published at the end of the competition hahahahahahah

        So current results (for tower) on the scoreboard can change after the contest? Even 100pts solutions?

          Don't take my words for the truth because there is nothing but rumours here: 100pts shouldn't be changed, and right now the checker is just checking whether the solution gets 100 points. So, anybody who has 100 has 100, and anybody who doesn't doesn't have.

            I am curious: is it already determined where the next EJOI will take place?

          Unfortunatly, No. Why you made so silly brute-forces problems? this is ejoi not codeforces.

          One of my all time favorite classic. Even thought i’ve spent 3 hours on it. I am really happy to score 100 points. Thank you for such an awesome problem.

          I quite liked it actually as a contestant! It was a bit easier than other problems, but still fine (and the task was fun).

    There is a solution in ceil(log2(N))+1. Subtract 1, go from most significant bit to least significant bit, if it's 1 then write "1 end", else write "2 end". Finally write "1 end".

    The results that are on the link right now should be the final ones (there is some room for appeals tomorrow also, but nothing major should happen), but better don't get me started on all the circumstances that were happening throughout the second day (several independent reasons) and the validity of aforementioned results. Though, guided by some reasons that are unknown to me, most of the countries voted on keeping these results on the discussion about whether second day should be counted in the final rankings.
