Then, you should binary search for the correct value. :) Edit: I think you should ternary search. :) |
|

There are many coders failed in problem B Div1 because they didn’t make enough iterations in the binary search. |
|

It’s O(n^3). |

What about the 24-hours qualification round? Will it be rated also? |
|

It should be “the 3rd of March”. :) |

TC Open has no upper limit for the age, and I think the lower limit is because of the money prizes and the onsite rounds. |
|

"The VK Cup Championship is an open computer programming competition" I don’t think this is an open competition, because of the age limit. |

I’m really sad because of the 23 years old limit, I’m 24. :( |

When will the system test start? |
|

According to the number of votes I got in the first comment, will you take it into considerations? |
|

I think it will be 4 points per minute, and the minimum score will be 300. |
|

I prefer if the problems are not sorted, just randomly shuffled. I think sorting the problems will ruin the experiment, just tell us after the contest what was your estimated difficulties, and see how correct is it. |

I don’t like these posts, a post in English to announce about something which will be in Russian only. |

Similar issue happened to me once in TopCoder, my Passed System Test solution during the contest is getting TLE in the practice room. :)

Optimism is much better than pessimism. :)

Don't be pessimistic! You can do it.

Can you make a PDF version of the problem statements?
|

Will Div1 and Div2 coders be mixed in the same rooms?

-660?! Is this a bug or someone created hundereds of accounts?

I don't agree with the randomization at all. If the reason of doing this is because some people think it's impossible for them to get a t-shirt, so I think the winner of the next TCO should be selected randomly. |

Yes it's. :( I wrote this line to debug something, but the sum array itself is long long. :(

How can I download a complete test case? I need to know what is test case 50 in problem B DIV1.

This is one of the best problem-sets I've ever seen in Codeforces. Thanks!

Maybe it's a hint for a problem in the contest. :P

I didn't understand your description, can you say an exact case?

Yes, it wasn't important.

Nice short-statements problem set!
Any one else didn't see the n.m<=40 constraint in C DIV-1? |
|

I'll add it again with new features. :)
|
|

I removed it, because the only feature was filtering by country, and Codeforces itself has this feature now.

It's fixed now. Thanks!

I don't think so.

Why the rates didn't get updated yet?

So, what is the correct approach?
|

Why?

I think you mean "standard".

What is "standart"?

Well, marriage in Egypt is done in 2 phases. The one before TCO round 3 is the real wedding.
Thanks! |
|

Oh no, maybe it will be hard for me (if I qualified), because round 3 will be just 1 day before my wedding. :)
|

I believe that participating in round 3 will not be that hard. :)

Also top 350 will get t-shirts.
|

I assume it will be just 1 problem set, because the contest name contains "Div. 1 + Div. 2".

ErosEthan's TopCoder handle is the same as his Codeforces handle. Do you know the TopCoder handle for flavio? Even if he is unrated.
|

This page may help: http://ahmed-aly.com/IOI2011
|

Isn't your TopCoder handle is random.johnnyh? I'm asking because of this.

As since the official language of the school is Russian, the registration requires knowledge of Russian. Also it is recommended to view this page in Russian. So why is this post translated to English? |
|

Yes you are correct, but we talked to Dr. Bill Poucher and he gave us an exception because it's out of our control and we did our best.
|

We have the same situation but with one member only. So most probable my team will have 2 contestants only.

Thanks! :) I wish to see everyone there too, as this will be my first and last world finals as a contestant. :) I'll be 24 years old in June 1st, just 1 day after the world finals. That's why it's my last world finals. |

See you there. :)

I made this Facebook question, so far TopCoder wins.

I have never seen TopCoder handling 2200 participants, and you are saying they can handle it easily!
The best example is after few hours, the maximum number of participants for TCO qualification round 1 is 2000. |

2011's round is still running. :)

Will use division separation for the next rounds?

"The registration will be opened during the whole contest."
This was written in the email which was sent to me about this round, but I see that the registration is closed. |

I know about it, but both sites are different.

Anyone, including those who didn't advance from the first qualification round
This is written about the second qualification round, does this mean anyone can participate in this round even if he is qualified from the first qualification round? |

It will contain a lot of math. :)

Actually I'll never try to read it. :)

Why is this contests still in the "Pay attention" table as running contest?

I think a big story could be a trouble and it could confuse someone, specially if the problem statement is not in his native language.
|
|

I'm with you that the problem statement should contain a story, but not very long one.
|
|

No, there isn't such functions. You need to implement your own balanced binary search tree for this.
|
|

In this problem it's the same, because I wanted to make an entry anyway if it doesn't exist.
I didn't write this statement as an if condition. |
|
0
Just to make an entry for name1 in the map, and it will be 0. Because I have to print all names even if the factor is 0.
If there is no entry for name1, nothing will happen. If there is no entry, it will be the same as factor[name1] = 0. |

Because you can only move to safe points, so you don't have any other choice.

By the way, Mostafa was in this contest, and he didn't solve this problem. It was just a joke with my best team-mate ever. :)

It should be. Did you find any test case which violates this rule?

The correct answer is YES, and your output is NO.

I used Google translate but I didn't understand everything, but it looks very interesting.
I'm waiting for the English translation. |

Because Petr's country in Codeforces is undefined, but it's Russian Federation in TopCoder.
And as you see in the main post, I used my TopCoder database to get the country for some users. Anyway, it's fixed now, you can check it here. |

I can do it for problems solved during contests only, even if he participated out of competition. Is this okay for you?

I had a stupid bug in my code, which cleared the country field for everyone.
I'm running the script which updates the countries again now, but it may take couple of hours. Sorry for this mistake. |

Why do you call this columns the most important?
Sorry, but I don't see it important at all. The gender, I can't get it from anywhere, just ask the person and this impossible to do for everyone. The real name, everyone is known by his username, who calls tourist Gennady Korotkevich? The city, why you may need to know the city for each one? You all are in the same country and this is the important thing. |

I've just updated 8 Iranian users in my database according to your table.
You can check the Iranian table here. |

It's updated now.
6 users from the Japanese table and 8 users from the Iranian table are now updated in my database. Thanks! |

If you have just added or changed your country, you can go to this page, and write your username and click update my country, and it will be updated in my database too.
You don't need to enter your country in my website, just update it in Codeforces and do the above steps. |

It's updated now.

I missed the contest because I stayed awake till 4:30 AM to finish this tool, and the contest was at 9:00 AM. :(

I had few problems in doing this: 1- It's optional for the user to write his country. (It should be mandatory) 2- The user will write the country in text box, then we can see two different countries "USA" and "United States of America", and maybe more than two. (It should be drop down list) 3- In each profile below the username, there is this string "FirstName LastName, Country, City". And any of these could be missing, so it may be "Country, City" or "FirstName LastName, Country". So I can't easily detect what is the country. (The country should be a constant field below the rating and contribution) |
