## 题意翻译

给你一个数字，将其“四舍六入”，末尾为5舍去或进位都可，求最终的数字。

## 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.

## 输入输出格式

The first line contains single integer $n$ ( $0<=n<=10^{9}$ ) — number that Vasya has.
