### Prompt

Develop a solution in Cpp to the problem described below:

Mr. Santa asks all the great programmers of the world to solve a trivial problem. He gives them an integer m and asks for the number of positive integers n, such that the factorial of n ends with exactly m zeroes. Are you among those great programmers who can solve this problem?

Input

The only line of input contains an integer m (1 ≤ m ≤ 100 000) — the required number of trailing zeroes in factorial.

Output

First print k — the number of values of n such that the factorial of n ends with m zeroes. Then print these k integers in increasing order.

Examples

Input

1


Output

5
5 6 7 8 9 

Input

5


Output

0

Note

The factorial of n is equal to the product of all integers from 1 to n inclusive, that is n! = 1·2·3·...·n.

In the first sample, 5! = 120, 6! = 720, 7! = 5040, 8! = 40320 and 9! = 362880.

### Response

```cpp
#include <bits/stdc++.h>
using namespace std;
int ceros(int n) {
  int count = 0;
  for (int i = 5; n / i >= 1; i *= 5) count += n / i;
  return count;
}
int main() {
  long long m, aux, cont = 0, auxNum;
  vector<long long> factoriales;
  vector<long long> vector;
  while (true) {
    aux = ceros(cont);
    vector.push_back(aux);
    if (aux > 100000) {
      auxNum = cont;
      break;
    }
    cont++;
  }
  cin >> m;
  int i;
  for (i = 0; i < auxNum; i++) {
    if (vector[i] == m) {
      factoriales.push_back(i);
    }
  }
  cout << factoriales.size() << " " << endl;
  for (i = 0; i < factoriales.size(); i++) {
    cout << factoriales[i] << " ";
  }
  return 0;
}
