I don't believe!!
var n,i:longint;
begin
readln(n);
if n>=1 then writeln((n+1)*n div 2)
else writeln((n+1)*(2-n) div 2);
end.

Oh, you are great programmer!

U are verry-verry clever person!!!

Nothing special. Everybody can see that. And I can reduce the length of prog by 1 byte(+)

change n>=1 into n>0 :)
