if your castling results looks like the normal king-side castle, it is called 0-0; if your castling results looks like a normal queen-side castling, it is called 0-0-0.

@saurav2202, I think it is 0-0 for you but it means the same because that is your only legal castle move.

I remember it as 0-0 (short side castle) and 0-0-0 (long side castle) - the king either castles on the side with fewer or more squares.
