Problem IBachet's Game

Bachet’s game is probably known to all but probably not by this name. Initially there are $n$ stones on the table. There are two players Stan and Ollie, who move alternately. Stan always starts. The legal moves consist in removing at least one but not more than $k$ stones from the table. The winner is the one to take the last stone. Here we consider a variation of this game. The number of stones that can be removed in a single move must be a member of a certain set of $m$ numbers. Among the $m$ numbers there is always $1$ and thus the game never stalls.

Input

The input consists of a number of lines. Each line describes one game by a sequence of positive numbers. The first number is $n \leq 1000000$ the number of stones on the table; the second number is $m \leq 10$ 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 either Stan wins or Ollie wins assuming that both of them play perfectly.
