Hello!

Welcom to the todays round! Note that this is last possibility to training before VK Cup on Codeforces — don't miss your chance! I hope, everybody will find interesting problems for him, you will not have misunderstanding with statements and there will have a harmony beteen your your solutions and our tests.

I'm an author of todays round. My name is Valeriy Samoylov, a graduated student of SPb SU. I want to thank Artem Rakhov (RAD) and Gerald Agapov (Gerald) for great help in investigation of problems.

And so I want to thank Maria Belova for translation of the statements and Alexanber Kouprin (Alex_KPR) for the statement prereading and the picture =)

Please, pay attantion to unusual problems cost in the first division:

500 — 1000 — 1500 — 2500 — 2500

And without surprise in the second division:

500 — 1000 — 1500 — 2000 — 2500

•  » » 7 years ago, # ^ |   +1 It definitely can, but not necessary. We can't assume for all of them do they tell truth or lie.
•  » » » 7 years ago, # ^ |   0 Thanks.I had misread the question ....Missed the part "you have to be absolutely sure..."
•  » » 7 years ago, # ^ |   +3 This is only one possible assignment. For your scenario the following are possible: T T L, T L T, L T T As you can see any suspect could have lied or told the truth, therefore it's undefined for all of them.
 » 7 years ago, # |   +3 Is system testing going to start soon? Or we can go sleep?
•  » » 7 years ago, # ^ |   +11 What about watching foorball this night?:)

 » 7 years ago, # |   0 1246567The output of double format in C# code is wrong. There is a comma(','), not a period('.').I think my solution is correct. but I got "wrong answer". is this a system problem or my fault?
•  » » 7 years ago, # ^ |   0 I think you have to set the locale of your program to "en-US", but still looks like you will get Wrong Answer.
•  » » 7 years ago, # ^ |   0 juancate is correct (in "but still looks like you will get Wrong Answer") — you are expecting, that the smallest circle is red, but it's not always truth
 » 7 years ago, # |   +7 Looking for the editorial... When will it be available?
•  » » 7 years ago, # ^ |   +2 Today in the evening or night.
•  » » » 7 years ago, # ^ |   0 When do you offer the editorial of the contest??
•  » » 7 years ago, # ^ |   +2 Russian editoral of your division have publicated already, you can use google translate. But it is better to wait to English version.
•  » » » 7 years ago, # ^ |   +3 Could you please provide direct link to the editorial?
 » 7 years ago, # |   +3 Does anybody know if the english version of the editorial is avaliable?
