eeeee.........
两个错误：
1.
```cpp
if((S2&a[i].big)==0) (g[a[i].S|S1][S2]+=g[S1][S2])%=mod;
if((S1&a[i].big)==0) (h[S1][a[i].S|S2]+=h[S1][S2])%=mod;
```
改为：
```cpp
if((S2&a[i].S)==0) (g[a[i].S|S1][S2]+=g[S1][S2])%=mod;
if((S1&a[i].S)==0) (h[S1][a[i].S|S2]+=h[S1][S2])%=mod;
```
2.
```cpp
if(now!=1) big=num;
```
改为
```cpp
if(now!=1) big=now;
```
