Again Twenty Five!

Description

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, ncan 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 ≤ 2·10¹⁸) — the power in which you need to raise number 5.

Output

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

Sample Input

Input

2

Output

25

题目意思：给你一个数n，让你求5^n的最后两位是什么，因为n>=2,很容易得出答案。

AC代码：

#include<stdio.h>int main(){int n;scanf("%d",&n);printf("25\n");return 0;}
