为啥提示我OLE，按理应该可以过

#include <bits/stdc++.h>
using namespace std;

int main()
{
    int n;
    cin >> n;
    for (int i = 1; i <= n; i++)
        cout << i << ' ';
    for (int i = 1; i <= n; i += 2)
        cout << i << ' ';
    for (int i = 2; i < n; i += 2)
        cout << i << ' ';
    return 0;
}
