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

I also got TLE, but when I added scanf() == 2 (input), I got accepted. |

100 is just a number, you want a multiple of this number e.g. 200, 300, 400, ..., but then, there are 'm' digit restrictions (in 2° example 1) and the digit is 0. With the restriction, the sentence would be like give me a number multiple of 100 BUT the number should not contain digit 0. It is impossible because 100, 200, 300, 1000 always gives contain 0, that's why the answer is -1. |
