#include <bits/stdc++.h>
using namespace std;
using ll = long long;
bool prime(int n) {
for (int i = 2; i * i <= n; i++) {
if (n % i == 0) {
return 0;
}
}
return 1;
}
int ans[1024];
int main() {
ios::sync_with_stdio(false);
cin.tie(nullptr);
for (int i = 2; i <= 1000; i++) {
if (prime(i)) {
int m = 0, v = i;
while (v) {
m |= 1 << (v % 10);
v /= 10;
}
if (!ans[m]) {
ans[m] = i;
}
}
}
for (int i = 0; i < 1024; i++) {
for (int j = 0; j < i; j++) {
if ((i & j) == j) {
if ((ans[j] != 0) && (!ans[i] || ans[i] > ans[j])) {
ans[i] = ans[j];
}
}
}
}
int n;
cin >> n;
int m = 1023;
for (int i = 0; i < n; i++) {
int k;
cin >> k;
if (m >> k & 1) {
m -= 1 << k;
}
}
cout << (ans[m] > 0 ? ans[m] : -1);
}
这程序好像有点Bug，我给组数据试试？
