1775 Problem 克隆人来了！

Description

克隆技术飞速发展，克隆人已经成为现实了！！所以，现在由你来编写一个Person类，来模拟其中的克隆过程。这个类具有2个属性：name——姓名（char*类型），和age——年龄（int类型）。

该类具有无参构造函数（人名为“no name”，年龄是0）、带参数构造函数、拷贝构造函数以及析构函数外，还有以下3个成员函数：

1. void Person::showPerson()：按照指定格式显示人的信息。

2. Person& Person::setName(char *)：设定人的姓名。

3. Person& Person::setAge(int)：设定人的年龄。

Input

输入分多行，第一行是一个正整数N，表示其后有N行输入。每行分两部分：第一部分是一个没有空白符的字符串，表示一个人的姓名；第二部分是一个正整数，表示人的年龄。

Output

呃~比较复杂，见样例吧！注意：要根据样例编写相应函数中的输出语句，注意格式哦！

Sample Input

3 Zhang 20 Li 18 Zhao 99

Sample Output

A person whose name is "no name" and age is 0 is created!

A person whose name is "Tom" and age is 16 is created!

A person whose name is "Tom" and age is 16 is cloned!

A person whose name is "Zhang" and age is 20 is created!

This person is "Zhang" whose age is 20.

A person whose name is "Zhang" and age is 20 is erased!

A person whose name is "Li" and age is 18 is created!

This person is "Li" whose age is 18.

A person whose name is "Li" and age is 18 is erased!

A person whose name is "Zhao" and age is 99 is created!

This person is "Zhao" whose age is 99.

A person whose name is "Zhao" and age is 99 is erased!

This person is "Zhao" whose age is 18.

This person is "no name" whose age is 0.

A person whose name is "Zhao" and age is 18 is erased!

A person whose name is "Tom" and age is 16 is erased!

A person whose name is "no name" and age is 0 is erased!

HINT

注意：输出中有“”！
