#include<iostream>
#include<cassert>
using namespace std;
const int LIM=1e5;
bool isnp[LIM+1];
int ans[1<<10];
int main()
{
ios::sync_with_stdio(false);
cin.tie(nullptr);
for(int i=0;i<1<<10;i++)ans[i]=-1;
for(int i=2;i<=LIM;i++)if(!isnp[i])
{
{
int u=i,v=0;
while(u>0)v|=1<<u%10,u/=10;
if(ans[v]==-1)ans[v]=i;
}
for(int j=i+i;j<=LIM;j+=i)isnp[j]=true;
}
for(int i=0;i<1<<10;i++)if(ans[i]!=-1)
{
for(int j=0;j<1<<10;j++)if((i&j)==i)
{
if(ans[j]==-1||ans[j]>ans[i])ans[j]=ans[i];
}
}
int n;cin>>n;
int ok=(1<<10)-1;
for(;n--;)
{
int d;cin>>d;
ok^=1<<d;
}
cout<<ans[ok]<<endl;
}
这程序好像有点Bug，我给组数据试试？
