c++的STL真的很方便，一个sort，一个求公约数函数就完事了
#include<bits/stdc++.h>
using namespace std;
int f(int b,int c)
{
if(c==0)
return b;
else return f(c,b%c);
}
int main()
{
int n;
while(scanf("%d",&n)!=EOF)
{
int a[n];
for(int i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
sort(a,a+n);
printf("%d %d %d\n",a[0],a[n-1],f(a[0],a[n-1]));

求公约数的时候，一定要从min开始j--，不能从1开始j++，否则的话会超时。
#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
int n;
while(cin >> n)
{
int a[n];
for(int i=0;i<n;i++)
{
cin >> a[i];
}
sort(a,a+n);
int min=a[0];
int max=a[n-1];
int yue;
for(int j=min;j>=1;j--)
{
if(min%j==0&&max%j==0)
{
yue=j;
break;
}
}
cout << min << " " << max << " " << yue << endl;
}
return 0;
