Takahashi is now X years old. Will his growth be celebrated in Shichi-Go-San this time?

-----Constraints-----
 - 1 ≤ X ≤ 9
 - X is an integer.

-----Input-----
Input is given from Standard Input in the following format:

-----Output-----
If Takahashi's growth will be celebrated, print YES; if it will not, print NO.

-----Sample Input-----
5

-----Sample Output-----
YES

The growth of a five-year-old child will be celebrated.
