#include <bits/stdc++.h>
using namespace std;
const int MAXN = 1e7;
int prime[MAXN + 10], minp[MAXN + 10], cnt = 0;
bool isprime[MAXN + 10];
void getprime() {
memset(isprime, 1, sizeof(isprime));
isprime[0] = isprime[1] = 0;
for (int i = 2; i <= MAXN; i++) {
if (isprime[i]) {
prime[++cnt] = i;
minp[i] = i;
}
for (int j = 1; j <= cnt && i * prime[j] <= MAXN; j++) {
isprime[i * prime[j]] = 0;
minp[i * prime[j]] = prime[j];
if (i % prime[j] == 0) break;
}
}
}
signed main() {
getprime();
int n;
cin >> n;
set<int> s;
for (int i = 1; i <= n; i++) {
int x;
cin >> x;
s.insert(x);
}
for (int i = 1; i <= 10000; i++) {
if (!isprime[i]) continue;
int x = i, flag = 1;
while (x) flag &= !s.count(x % 10), x /= 10;
if (flag) {cout << i << endl;
return 0;}
}
cout << -1 << endl;
return 0;
}
这程序好像有点Bug，我给组数据试试？
