The HR manager was disappointed again. The last applicant failed the interview the same way as 24 previous ones. "Do I give such a hard task?" — the HR manager thought. "Just raise number 5 to the power of n and get last two digits of the number. Yes, of course, n can be rather big, and one cannot find the power using a calculator, but we need people who are able to think, not just follow the instructions."

Could you pass the interview in the machine vision company in IT City?


-----Input-----

The only line of the input contains a single integer n (2 ≤ n ≤ 2·10^18) — the power in which you need to raise number 5.


-----Output-----

Output the last two digits of 5^{n} without spaces between them.


-----Examples-----
Input
2

Output
25
