把数组定义在主函数内可不是个好习惯

@[lyc1213](/user/636692) 谢谢前辈，前辈能帮我看看代码吗，我的第十个测试点wa，给的OUT数据和我测的数据是一样的。

我也很奇怪，我正在看你的代码。

还有，您大可不必喊我前辈。

“十年OI一场空，不开long long见祖宗。”开个long long就好了（亲测有效）。
Code
```cpp
#include <iostream>
using namespace std;
long long a[102];
int main() {
long long n;
long long sum = 0;
cin >> n;
for (long long i = 0; i < n + 1; i++) {
cin >> a[i];
if (a[i] == 0) {
sum++;
continue;
}
if (sum != i) {
if (a[i] > 0)
cout << "+";
}
if (a[i] != 1 && a[i] != -1) {
cout << a[i];
}
if (a[i] == -1 && i != n)
cout << "-";
if (i < n)
cout << "x";
if (i < n - 1)
cout << "^" << n - i;
if (a[n] == -1 || a[n] == 1)
cout << a[n];
}
return 0;
}
```

绝了，改成long long 就过了，谢谢！
