规则函数写错了，应改成：
```cpp
void pd(int aa,int bb){
if(aa == 0){
if(bb == 2 || bb == 3)cnta++;
else if(bb == 1 || bb == 4)cntb++;
}
else if(aa == 1){
if(bb == 3 || bb == 0)cnta++;
else if(bb == 2 || bb == 4)cntb++;
}
else if(aa == 2){
if(bb == 4 || bb == 1 )cnta++;
else if(bb == 0 || bb == 3)cntb++;
}
else if(aa == 3){
if(bb == 2 || bb == 4 )cnta++;
else if(bb == 0 || bb == 1)cntb++;
}
else if(aa == 4){
if(bb == 0 || bb == 1)cnta++;
else if(bb == 2 || bb == 3)cntb++;
}
}
```
还有就是cnta和cntb要初始化为**0**
