#include <bits/stdc++.h>
using i64 = long long;
constexpr int M = 10;
constexpr int N = 5e7 + 10;
bool ntprime[N];
int prime[N], tot;
bool inside[M];
void sieve() {
for (int i = 2; i < N; i++) {
if (!ntprime[i]) {
prime[++tot] = i;
}
for (int j = 1; j <= tot && i * prime[j] < N; j++) {
ntprime[i * prime[j]] = true;
if (i % prime[j] == 0)
break;
}
}
}
int main() {
std::ios::sync_with_stdio(false);
std::cin.tie(nullptr);
int n;
std::cin >> n;
for (int i = 0; i < n; i++) {
int p;
std::cin >> p;
inside[p] = true;
}
sieve();
for (int i = 1; i <= tot; i++) {
int t = prime[i];
bool flag = true;
while (t) {
if (inside[t % 10]) {
flag = false;
break;
}
t /= 10;
}
if (flag) {
std::cout << prime[i] << '\n';
return 0;
}
}
std::cout << "-1" << '\n';
return 0;
}
这程序好像有点Bug，我给组数据试试？
