输入：
```
5
5 4 3 2 1 0
```
read：
```
5x^5+4x^4+3x^3+2x^2+1x^10
```
expected：
```
5x^5+4x^4+3x^3+2x^2+x
```
问题蛮多的（（
这是我的代码（稍微长了那么~~亿~~一点点）：
```cpp
#include <iostream>
using namespace std;
int n, t, m;
int main(){
cin >> m;
n = m;
if(n == 0){
cout << "0" << endl;
return 0;
}
while(n != -1){
cin >> t;
if(n == 0){
if(t > 0){
cout << "+" << t;
} else if(t < 0){
cout << t;
}
} else {
if(n == m){
if(t > 0){
if(t == 1){
if(n != 1) cout << "x^" << n;
else cout << "x";
} else {
if(n != 1) cout << t << "x^" << n;
else cout << t << "x";
}
} else if(t < 0){
if(t == -1){
if(n != 1) cout << "-x^" << n;
else cout << "-x";
} else {
if(n != 1) cout << t << "x^" << n;
else cout << "t" << "x";
}
}
} else {
if(t > 0){
if(t == 1){
if(n != 1) cout << "+x^" << n;
else cout << "+x";
} else {
if(n != 1) cout << "+" << t << "x^" << n;
else cout << "+" << t << "x";
}
} else if(t < 0){
if(t == -1){
if(n != 1) cout << "-x^" << n;
else cout << "-x";
} else {
if(n != 1) cout << t << "x^" << n;
else cout << t << "x";
}
}
}
}
n--;
}
return 0;
}
