Hello everyone! Recently, I decided to spend a little of my precious time on such an easy competition as the IOI, and, honestly, I found the results absolutely disappointing. While I had already come up with ideas for all the problems and solved them within three minutes, the participants of this competition couldn't even figure out the solution to the second problem, which led me to believe that they didn't even try when writing this competition.

In light of the above statement, I would like to conclude: if I had enough free time, I would have absolutely dominated the IOI and, lowkey, taken first place without putting in any effort whatsoever.
