代码清单：
#include<iostream>
using namespace std;
class axxx
{
public:
void px(int n,int a[])
{
for(int i=0;i<n;i++)
{
for(int j=0;j<n-i-1;j++)
{
int t;
if(a[j]>a[j+1])
{
t=a[j];
a[j]=a[j+1];
a[j+1]=t;
}
}
}
}
void px(int n,double b[])
{
for(int i=0;i<n;i++)
{
for(int j=0;j<n-i-1;j++)
{
double t;
if(b[j]>b[j+1])
{

b[j]=b[j+1];
b[j+1]=t;
}
}
}
}
};
int main()
{
int n;
cin>>n;
axxx c1;
int a[n];
for(int i=0;i<n;i++)
cin>>a[i];

for(int i=0;i<n;i++)
{
cout<<a[i]<<" ";
}
cout<<endl;
for(int i=0;i<n;i++)
cout<<b[i]<<" ";
