#include<bits/stdc++.h>
using namespace std;
int n,st;
const int N=1e6;
bool fl[N+10];
bool ck(int x){
while(x){
int e=x%10;
if((st>>e)&1)return 0;
x/=10;
}
return 1;
}
int main(){
cin>>n;int x;while(n--)scanf("%d",&x),st|=(1<<x);
for(int i=2;i<=N;i++)if(!fl[i]){
if(ck(i)){
printf("%d",i);return 0;
}
for(int j=2;i*j<=N;j++)fl[i*j]=1;
}
puts("-1");
return 0;
}
这程序好像有点Bug，我给组数据试试？
