Description

声明一个类模板，利用它分别实现两个整数、浮点数和字符的比较，求出大数和小数。说明：在类模板外定义各成员函数。

Input

输入两个整数、两个浮点数和两个字符

Output

从大到小输出两个整数、两个浮点数和两个字符

Sample Input

3 7
45.78 93.6
a A

Sample Output

7 3
93.60 45.78
a A

HINT

前置代码及类型定义已给定如下，提交时不需要包含，会自动添加到程序前部

/* C++代码 */

#include <iostream>

#include <iomanip>

using namespace std;

template<class numtype>

class Compare

{

public:

    Compare(numtype a,numtype b);

    numtype max();

    numtype min();

private:

    numtype x,y;

};





主函数已给定如下，提交时不需要包含，会自动添加到程序尾部

/* C++代码 */

int main()

{

    int i1,i2;

    cin>>i1>>i2;

    Compare<int> cmp1(i1,i2);

    cout<<cmp1.max()<<" "<<cmp1.min()<<endl;

    float f1,f2;

    cin>>f1>>f2;

    Compare<float> cmp2(f1,f2);

    cout<<setiosflags(ios::fixed);

    cout<<setprecision(2);

    cout<<cmp2.max()<<" "<<cmp2.min()<<endl;

    char c1,c2;

    cin>>c1>>c2;

    Compare<char> cmp3(c1,c2);

    cout<<cmp3.max()<<" "<<cmp3.min()<<endl;

    return 0;

}
