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.

题目大意:输入整数n,输出所有满足阶乘后缀有n个0的数

题解:10是由5*2得来,既找出阶乘的因子有几个5(5>2,有5就有2)

#include <bits/stdc++.h>
using namespace std;
int main()
{
    int a, i, n, n1, j;
    scanf("%d", &n);
    ;n>;i++)
        {
        n1=i;
        ==)
            {
                n1 /= ;
                n--;
            }
        }
    )
        printf("0\n");
    else
    {
        printf("5\n");
        ;j<=i+;j++)
            printf("%d ", j);
        printf("\n");
    }
    ;
}
