rt，如下代码为啥说Can not open player's output file!呢？是文件输入输出写挂了吗？

#include <iostream>
#include <cstdio>
#include <cmath>
using namespace std;
int a[100000010];
int main(){
	freopen("divide.in","r",stdin);
    freopen("divide.out","w",stdout);
	int T;
	cin >> T;
	while(T--){
		int n;
		cin >> n;
		int t = 0;
		int k = sqrt(n);
		int ans = 0;
		for(int i = 1;i <= k;i++){
			ans++;
			if(n / i != i)t++,a[t] = n / i;
		}
		ans += t;
		cout << ans + 1 << endl << 0 << " ";
		for(int i = 1;i <= k;i++)cout << i << " ";
		for(int i = t;i >= 1;i--)cout << a[i] << " ";
		cout << endl;
	}
	return 0;
}
