#include <bits/stdc++.h>
int main() {
std::cin.tie(NULL);
std::iostream::sync_with_stdio(false);
int N;
std::cin >> N;
if (N >= 10) {
std::cout << 10;
return 0;
}
std::set<int> inside;
int mex = 1;
for (int i = 1; i <= N; i++) {
int val = i;
int rev = 0;
while (val > 0) {
rev = rev * 10 + val % 10;
val /= 10;
}
inside.insert(rev);
}
while (inside.find(mex) != inside.end()) mex++;
std::cout<< mex;
return 0;
}
这程序好像有点Bug，我给组数据试试？
