University of Sao Paulo (Campus Sao Carlos) holds a qualifier contest every year to select participants that will represent our university on the ACM-ICPC Brazilian Sub Regionals.
This year, the contest will take place on August 19th at 14:00 BRT. The contest is public and everyone is welcome to participate on Codeforces Gym.
This year problem setters are bimaoe, danft, ffao, LaercioJr, Seku, tomasf, and me (teochaban). We would like to thank joaogui1, andre_smaira and overnite.runner for helping us out with testing and reviewing.
The problem set is supposed to keep both starters and veterans entertained, but it's probably too easy for grandmasters. It was designed for solo participants.
Here are our contests from past years:

Any idea on Problem H?
