帮看一下这个程序呗
```cpp
#include<iostream>
using namespace std;
int main()
{
int n;
cin>>n;
int m;
cin>>m;
bool b=false;
if(n==0) cout<<m;
else if(n==1&&m==1||m==-1&&m!=0) cout<<"x";
else if(n==1&&m!=1&&m!=0) cout<<m<<"x";
else if(m!=0&&n!=0&&n!=1) cout<<m<<"x^"<<n;
else if(n!=0&&n!=1&&m==1) cout<<"x^"<<n;
else if(n!=0&&n!=1&&m==-1) cout<<"-x^"<<n;
else b=true;
for(int i=n-1;i>=1;i--)
{
cin>>m;
if(m==0) continue;
else if(m==1&&i!=1&&b!=true) cout<<"+x^"<<i;
else if(m==-1&&i!=1) cout<<"-x^"<<i;
else if(m>1&&i!=1&&b!=true) cout<<"+"<<m<<"x^"<<i;
else if(i==1&&m==1&&b!=true) cout<<"+x";
else if(i==1&&m>1&&b!=true) cout<<"+"<<m<<"x";
else if(m==-1&&i==1) cout<<"-x";
else if(i==1&&m<1&&b!=true) cout<<m<<"x^"<<i;
else if(i!=1&&m!=1&&m!=-1&&b!=true&&m<-1) cout<<m<<"x^"<<i;
else if(m==1&&i!=1&&b==true) cout<<"x^"<<i;
else if(m>1&&i!=1&&b==true) cout<<m<<"x^"<<i;
else if(i==1&&m==1&&b==true) cout<<"x";
else if(i==1&&m>1&&b==true) cout<<m<<"x";
else continue;
b=false;
}
if(n!=0)
{
cin>>m;
if(m>0) cout<<"+"<<m<<endl;
else if(m<0)cout<<m<<endl;
}
return 0;
}
