我的代码如下：

#include <iostream>
using namespace std;

int a[1005], b[1005];

int main()
{
    int n;
    cin >> n;
    int i = 2;
    while (n > i)
    {
        a[i - 1] = i;
        n -= i;
        i++;
    }
    i -= 2;
    int j = i;
    while (n != 0)
    {
        a[j]++;
        n--;
        j--;
    }
    b[1] = a[1];
    b[0] = 1;
    for (j = 2; j <= i; ++j)
    {
        int w = 0;
        for (int k = 1; k <= b[0]; ++k)
        {
            b[k] = b[k] * a[j] + w;
            w = b[k] / 10;
            b[k] %= 10;
        }
        while (w != 0)
        {
            b[++b[0]] = w % 10;
            w /= 10;
        }
    }
    for (int j = 1; j <= i; ++j)
    {
        cout << a[j] << " ";
    }
    cout << endl;
    for (int j = b[0]; j >= 1; --j)
    {
        cout << b[j];
    }
    return 0;
}
