```
//次高次项~n-2次项
for(int i=1;i<=n-2;i++){
if(a[i]==1)cout<<"x^"<<n-i;
else if(a[i]==0)continue;
else if(a[i]==-1)cout<<"-x^"<<n-i;
else if(a[i]>1)cout<<"+"<<a[i]<<"x^"<<n-i;
else cout<<a[i]<<"x^"<<n-i;
}
```
中
```
if(a[i]==1)cout<<"x^"<<n-i;
```
应该为
```
if(a[i]==1)cout<<"+x^"<<n-i;
```
我试了一下，还没有评测出来，您可以试一下
