Is the testdata changed? I submit a solved program many times, but always get wa

Who Can Post a just-solved program, I think it is hard to solve this
problem now.

I have tried my AC solution and it got WA! I suppose the test cases have really been changed. (+)

Here's my code which got AC before ...

Program Polynom;
Var i,n:Word;
Begin
Readln(n);
Writeln(0);
For i:=1 To n Do Begin
Writeln('x');
Writeln('*');
Writeln(i);
Writeln('+');
End;
End.

Wu...........What Shall I Do??? I have submitted this problem for more than 20 times.

Does it mean that your solution is wrong?

Same code, different results. Can any1 who got this question AC pls post source code?

My code is almost identical, but...

program expression;
var
i,j:word;

begin
readln(j);
writeln(0);
for i := 1 to j do begin
writeln('X');
writeln('*');
writeln(i);
writeln('+');
end;
end.

It gets Wrong Answer no matter whether the variables are integers or
words(the data types) . Does anyone know what is wrong with my code?
Also, if you have this problem accepted, i'll be most grateful if u
posted the source codes here, since i havent the faintest idea what
the question says and wants

In fact, this solution is really wrong. I don't understand how it
could get AC before.

I got AC lately for this problem.
This is my solution:

var
    N:integer;
   i:integer;

begin
   readln(N);
   if n=0 then writeln(0) else
   begin
      writeln('0');
      writeln('X');
      writeln('*');
      for I:=1 to n-1 do
      begin
         writeln(i);
         writeln('+');
         writeln('X');
         writeln('*');
      end;
      writeln(n);
      writeln('+');
   end;
end.

And that is all...
