Dear Friends!

If you dream of realizing your ideas in new technologies and products used by a third part of the world's population — join Honorcup Marathon. It will be an unrated round for individual participation, as well as for teams of up to three people.

Take part in the round →

You will develop new method for determining blood pressure. The standard procedure for measuring blood pressure requires about a minute, during which the cuff compresses the artery in the hand. Since the procedure is relatively sophisticated, simpler methods of blood pressure estimation are potentially of great value. We suggest that you learn how to determine blood pressure based on the data from optical methods to determine changes in blood volume in the finger. Perhaps, your proposal will be implemented in one of Huawei products, and thereby help users reduce the risks of heart and vascular diseases!

At stake: high paid internships in Moscow, St. Petersburg or China (including transportation & accommodation expenses if needed). Also we have 9 smartphones for top 9 results:

  • 1-3 place: Huawei P20 Pro
  • 4-6 place: Huawei P20
  • 7-9 place: Honor 10

And, of course, TOP 30 participants will get T-shirts with Honorcup Marathon logo!

We accept solutions before 4th October, 19.59.59, Msc time. Winners will be awarded on 20th of October during the opening ceremony of 1/4 ICPC 2018 in Nagatino, Msk.

We will ask winners to provide the source code and description of the solution; the details can be discussed in a phone call. In case of reasonable doubt about the violation of the rules, we reserve the right to transfer the prize to the next participant. Thank you for understanding!

Don’t miss your chance!

Good luck to all!

What is "Huwei P20 Pro"? This typo should be corrected as soon as possible. :)

[UPD] It seems that it is corrected now. BTW, "Huawei" P20 Pro is a great mobile phone actually. :P

    I suspect Huawei will present Huwei P20 Pro which he bought in Pinduoduo:-P(just joking)

The standing should show one's lowest score instead of the highest :P

      Right now a score of "0 X X" is above "X 2737.445 X" in the ratings. I assume 0 is not actually a valid score, but rather an attempt that failed in some way, so it should be sorted as "X" in the rankings. Would you agree?

      (Above, 'X' stands for 'no attempt'.)

If you are a team of 3 and win, do you still get one phone in total?

      As I understand, "Yes" for the both questions. In general, we assume individual participation, but we decided not to limit those who wish to work in a team.

    You can participate individually and if every of you is strong and active enough, maybe you can take 3 phones and 3 t-shirts.

Results seems to be ordered by decreasing of score. But in practice it is not so. Not even by increasing.

    I think it is ordered according to the "hidden score" on C.

hello all, please, what is the meaning of "text" language ?

    It means that the only allowed submission language is raw text. If you look at the problem statement underneath "Output", you'll see exactly how the text should be formatted.

    Because you only need to submit the output, you can use any programming language or application you like to predict and/or calculate the SBP and DBP values.

I think, there is some issue with the результаты . Neither they are based on total score nor based on the score of problem-B.

Edit: Got it. All those who submitted problem-C are above those who didn't. And they are sorted by increasing total score(which includes problem-A score in some cases).

The standing sort for sum of A and B tasks, but it's not so good.
