烦死了
```cpp
#include<cstdio>
int main()
{
int n;
int a;
int f=-1;
scanf("%d",&n);
int m=n+1;
while(m--)
{
if(m<0)
break;
scanf("%d",&a);
f=a;
if(a!=0)
{
if(f>=0&&m!=n)
printf("+");
if(a!=1&&a!=-1&&m!=0)
printf("%d",a);
else if(a==-1&&m!=0)
printf("-");
if(m>1)
printf("x^%d",m);
else if(m==1)
printf("x");
else
printf("%d",a);
}
}
return 0;
}
```
