About Codeforces Beta Round #47
By MikeMirzayanov, 14 years ago, translation, In English

Good evening… (good?)

There were difficulties with the round, for which I apologize. During the contest I was able to partially locate the troubles, I hope we’ll fix them soon. Apparently, there were two troubles: 1) site didn’t respond, 2) for hacking attempts occurred inappropriate message that hacking is already taken. We will investigate it. Thank you for your patience.

So we decided to do it unrated.

I added work to the next round, the more so because I'm going to be its author:)

By following your link , I got this http://www.codeforces.com/blog/entry/417?locale=ru , I will now use Visual C++. 

No need of  C and C++(gnu) altogether.

    Is  %s  also a problem?

    Because this code passed on MS C++ but not on GNU .

    PROBLEM B.

    #include<vector>
    #include<map>
    #include<iostream>
    #include<algorithm>
    #include<stdio.h>
    using namespace std;
    int main()
    {
    map<char,long long int> c;
    long long int ans;
    long long int i;
    char s[100001];
    scanf("%s",s);
    i=0;
    while(s[i]!='\0')
    {
    c[s[i]]++;
    i++;
    }
    ans=0;
    for(i=0;i<c.size();i++)
    {
    ans+=c[i]*(c[i]-1)+c[i];
    }
    cout<<ans;
    scanf("%*d");
    return 0;
    }

Ah it's better that this contest is unrated, I couldn't access the site at all during the contest even for submissions!
It was like waiting in queue trying to refresh the page in hope to see when I get a chance to submit, in the end I got two problems solved (I came to know what problem E was only after the contest got over!), I think codeforces is getting too popular and there is something participants should do, like donate some amount to you so you can buy a new server?

    Codeforces is sponsored by vk.com I think that if you would like to help, prepare problems for contests and think of potential improvements.

I think Codeforces should get powerful servers or restrict the number of participants in a contest to avoid such problems in the future. The distribution in rooms also should be based on rating and not random. Yesterday I had many red-rated coders (including tourist) and many yellow-rated coders in my room.
This was my best performance on Codeforces and now its unrated.. :(
