102510: [AtCoder]ABC251 A - Six Characters

Problem Statement

You are given a string $S$ consisting of lowercase English characters. The length of $S$ is between $1$ and $3$, inclusive.

Print the string of length $6$ that is a repetition of $S$.

It can be shown that there uniquely exists such a string under the Constraints of this problem.

Constraints

• $S$ is a string consisting of lowercase English characters of length between $1$ and $3$, inclusive.

Input

Input is given from Standard Input in the following format:

$S$

Output

Print the answer string, which is of length $6$.

Sample Input 1

abc

Sample Output 1

abcabc

These are strings that are repetitions of $S = $ abc: abc, abcabc, abcabcabc, abcabcabcabc, and so on. Among them, abcabc has the length of $6$, so abcabc should be printed.

Sample Input 2

zz

Sample Output 2

zzzzzz

问题描述

你得到了一个由小写英文字母组成的字符串$S$。字符串$S$的长度在1到3之间，包括1和3。

打印长度为6的字符串，它是$S$的重复。

可以证明，在本问题的约束下，这样的字符串是唯一存在的。

约束

• $S$是一个由小写英文字母组成，长度在1到3之间的字符串。

输入

输入通过标准输入给出以下格式:

$S$

输出

打印答案字符串，长度为6。

样例输入1

abc

样例输出1

abcabc

这些是字符串$S=$ abc的重复: abc, abcabc, abcabcabc, abcabcabcabc, 等等。其中，abcabc的长度为6，所以应该打印abcabc。

样例输入2

zz

样例输出2

zzzzzz
