Нужна паскаль, составить прогу чтобы можно было вводить n и она выводила результатНУЖЕН ТОЛЬКО В)

#include <iostream>

#include <vector>

#include <cmath>

using namespace std;

double fac(double k){

   if(k == 1)

       return 1;

   return k * fac(k-1);

}

signed main(){

   int n;

   cin >> n;

   double sum = 0;

   double k = 1;

   for(k; k <= n; k++)

       sum += 1/fac(pow(k,2));

   cout << sum;

}

Дан во вложении.
