633_B. A Trivial Problem
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.
```python
from math import log
n = int(input())

def fivetorization(n):
	cnt = 0
	while n%5==0:
		cnt+=1
		n//=5
	return cnt

res=0
for i in range(5, 500001, 5):
	res+=fivetorization(i)
	if res==n:
		print(5)
		print(*[j for j in range(i, i+5)])
		quit()
print(0)
```
