#include "bits/stdc++.h"
using namespace std;

int main() {
    int n, k, D[10];
    cin >> n >> k;
    for (int i = 0; i < 10; i++) D[i] = 0;
    for(int i = 0; i < k; ++i) {
        int d; cin >> d;
        D[d] = 1;
    }


    int pay = n;
    int digits = 0;
    while (n > 0) {
        int d = n % 10;
        if (D[d]) {
            int i = d + 1;
            while (i < d + 10) {
                if (D[i % 10] == 0) break;
                i++;
            }
            int dx = i - d;
            n += dx;
            pay += dx * pow(10, digits);
        }
        digits++;
        n /= 10;
    }

    cout << pay << endl;

    return 0;
