MULTII  Yet Another Multiple Problem
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.
Input
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.
Output
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.
Example
Input: 2345 3 7 8 9 100 1 0 Output: Case 1: 2345 Case 2: 1

Got RTE when trying to print the number recursively. This is a general request  can the Java stack be increased?
