Let $S$ and $T$ be two non-empty subsets of $R$. If there exists a function $y = f(x)$ from $S$ to $T$ such that:
(i) $T = {f(x) | x \in S}$;
(ii) For any $x\_1$, $x\_2 \in S$, if $x\_1 < x\_2$, then $f(x\_1) < f(x\_2)$,
then these two sets are said to be "order-preserving isomorphic". Now, among the following three pairs of sets:
(1) $A = N$, $B = N^*$;
(2) $A = {x | −1 \leqslant x \leqslant 3}$, $B = {x | −8 \leqslant x \leqslant 10}$;
(3) $A = {x | 0 < x < 1}$, $B = R$.
The sequence number of the "order-preserving isomorphic" set pairs is $\_\_\_\_\_\_$.
