Problem A: 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

3Zhang 20Li 18Zhao 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“”！
