Hi, everybody!
Welcome to the "Codeforces Beta Round #40 (Div. 2)". Let the weather cloudy (at least in Saratov), and the round began with the unavailability of the server (we apologize for a fail), but I hope the tasks will bring you pleasure.
Wish you high ratings,
MikeMirzayanov
I think you have trouble in this part of your code:
<pre>
if(input.Substring(i,2)=="at")
{
input=input.Substring(0,i)+"@"+input.Substring(i+2);
}
</pre>
reread the statement carrefully ;)
yep :)
small mistake.
but what will be the answer for such test:
dotdotatatatatatatatdotdot
?
(Sorry! you did not ask the really ans. My mistake)

really nice problems!
thanks to authors and CodeForces!
well done!
I think there will be many pepele died in problem B.
!
Yeah, the problem is simple .Many people make a mistake on what the problem mean.
But finally i got WA...
Does the problem means, i can buy many times, but sell only once?
1 2 1 2 you could get more than 8 using 2 sells and buys. By the way, that's a test, which gave me 3 hacks :P
when greedy, use:
int cas = b / min[i];
int t = b + cas * (data[i] - min[i]);
if (t > max) max = t;
min[i] is the min number in the left side.
(bug: commenting seems to not work (comment is blank) from chromium?)
Can there be more than one word in problem A
nope
