Problem А. STL + little brain.
• map<string,int> M_pair; // data in put M_pair;
• map<string,vector<pair<int,int> > > M_step; // step of player;
• vector<pair<int,string> > Res; // first - result game, second name of player ;
• sort(Res.being(),Res.end(),predicat); // created the predicate for which there is a sort Res, players;
• predicat //if you win the same, then look at M_step chronology of events when a player has earned the first time, the amount m;
Problem В. no opinion((
first suggested to avoid the numbers 2,5,10 ie those who create the zeros, but seeing the test realized that
is not correct.
Problem С. I understand it correctly???
The three circles on the field and need to find a point equidistant from the three circles?

Even though I solved the problem A two hours, I liked the process =) Please help me!)
