Did i understand the problem? I don't think so. My answer
is always larger than 1*10^5. But I know your answers are
smaller than 10^4;
Could anyone help me?

There was MaxLongInt constant, in Pascal it is 2^31 -1.
To avoid any misunderstandings, I have put the exact number
in the problem source.

P.S. 2^31 is about 2 billion.
