Problem:

Initially there are n stones on the table. There are two players Pablo and Chris, who move alternately. Pablo always starts. The number of stones that can be removed in a single move must be a member of a certain set of m numbers. The winner is the one to take the last stone. If both of two players can not remove all the stones on the table, they make a draw. Assume that both of them play perfectly.

Input:

The input consists of a number of lines. Each line describes one game by a sequence of positive numbers. The first number is n <= 100000 the number of stones on the table; the second number is m <= 10 giving the number of numbers that follow; the last m numbers on the line specify how many stones can be removed from the table in a single move.

 

Output:

 

For each line of input, output one line saying 1. Pablo wins 2. Chris wins 3. Draw according to the constraint above.
