Sorry, I don`t know special inputs for this problem. But I can see your code and will try to find mistake. One problem: I know only Pascal :(
And if your program in another source I can`t check it. But maybe somebode else will help you.

Euler`s Function

First of all this is math problem.
f(n) - number of positive integers less than n are relatively prime to n.
This is Euler`s Function.
If n=(p1^a1)*(p2^a2)*...*(pk^ak) where p1, ..., pk - prime numbers than f(n)=n*(1-1/p1)*(1-1/p2)*...*(1-1/pk) .
I think it may help you.

Hi!
I also had this problem, but when I change
[pascal]
for i:= 1 to n do write(a);
writeln;
writeln;
[/pascal]
to
[pascal]
var s: string;
...
s:='';
for i:=1 to n do s:=s+chr( a + 48 );
writeln(s);
if qual<quality then writeln;[/pascal]
And I`ve got AC(not PE) in 1 sec :P

Hm...

You have to find the sum of two numbers with maximal size of 1.000.000 digits.
I think your code can`t solve numbers that have 1000000 digits. Isn`t it? :-?
