Hello.
Last Satuday we had the Brazilian Sub Regionals for ICPC 2015/16, an online contest was held at the same day on uva online judge.
I'm creating this post so we can discuss the contest problems.
Can anyone give me a hint on how to solve "I — Ominobox", "G — Curious Guardians" and "L — Lottery"?
(The other problems we either have solved during the contest or have solved after, so if you need help with any other one, let me know)
