We are glad to invite you to participate in today’s round.
Problems have been prepared by poopi, Mohammad_JRS, Gerald and me. The hero of our contest is called “PMP”. It is actually the base of our team name through the last five years. The stories are metaphoric, but they have some traces in truth.
This Codeforces round, is the last round before the incoming ICPC world final. Our best wishes for all participants of that contest, too.
And we have a modified version of Burunduk1 ’s advice: “to make the round even more interesting for us, read the statements of ALL problems.” :)
We hope you enjoy the problems and have high ratings.
Update: Contest is over. Thanks to everyone for taking part and congratulations to the winners of both divisions, specially peter50216 for being the only who solved all the problems of division 1! :)
