MULTII - Yet Another Multiple Problem

no tags 

Given a positive integer N (1 <= N <= 10000) and some digits, find the smallest positive multiple of N whose decimal notation does not contain any of the given digits.


Each test case contains two lines. The first line contains two integers N and m separated by a single space. The second line contains m digits separated by spaces. Input terminates by EOF.


For each test case output its case number (starting from 1) and the answer in a single line, or "-1" (without quotes) if the answer doesn't exist.


2345 3
7 8 9
100 1

Case 1: 2345
Case 2: -1

Ok, I give up, this problem is too hard for me for now...
In case like this:
2791 9
0 2 3 4 5 6 7 8 9
answer is not -1 but answer is 1111111111111111111111111111111
so it's very large integer :-O
