题目描述
Vasya has a non-negative integer $n$ . He wants to round it to nearest integer, which ends up with $0$ . If $n$ already ends up with $0$ , Vasya considers it already rounded.
For example, if $n=4722$ answer is $4720$ . If $n=5$ Vasya can round it to $0$ or to $10$ . Both ways are correct.
For given $n$ find out to which integer will Vasya round it.
For example, if $n=4722$ answer is $4720$ . If $n=5$ Vasya can round it to $0$ or to $10$ . Both ways are correct.
For given $n$ find out to which integer will Vasya round it.
输入格式
The first line contains single integer $n$ ( $0<=n<=10^{9}$ ) — number that Vasya has.
输出格式
Print result of rounding $n$ . Pay attention that in some cases answer isn't unique. In that case print any correct answer.
