Codechef June Lunchtime 2017

On Saturday, Codechef June Lunchtime 2017 took place. I wrote the editorials for the contest and have to tell you that at least 2 problems were quite interesting, and one of them exceptionally hard! If you take a look at the final standings, you'll see that only 3 people solved all problems during the contest, and we had very strong participants as usual. My bet was that nobody will solve it, but fortunately, I was wrong :)

If you didn't participate and want to practice problem-solving skills, I recommend trying COMPCLUB problem, or if you want something really hard, then try SHDWCMP.

My editorials are available here.
