вернуться в форумHelp! Why wrong answer? Послано aaa 22 мар 2002 15:35 I've got trouble in 1200.
Help me please.
Here is my programme:
{$n+}
const zero=1e-5;
var k,c,d,e,f:longint; a,b,max,g:extended;
begin
assign(input,''); reset(input);
assign(output,''); rewrite(output);
read(a,b); read(k);
max:=-1e10;
for c:=0 to k do begin
d:=round(b/2);
if d<0 then d:=0;
if c+d>k then d:=k-c;
g:=-sqr(d)+b*d+a*c-sqr(c);
if g>max-zero then begin
max:=g; e:=c; f:=d;
end;
end;
writeln(max:0:2); writeln(e,' ',f);
close(input); close(output);
end.
Thank you very much! Sorry,I post a wrong programme. Here is the currunt one. Help me! Послано aaa 22 мар 2002 15:45 {$n+}

end. Re: Sorry,I post a wrong programme. Here is the currunt one. Help me! Use trunc, not round.
Don't use const zero, only need " if g > max ".
I'm sure you'll get AC Thank you for your help! Послано aaa 23 мар 2002 05:45 Could you tell me why use trunc(b/2) instead of other value? I think there maybe some maths reason. Послано aaakkk 19 ноя 2002 08:35 > Use trunc, not round.
