Problem Description

Stan and Ollie play the game of multiplication by multiplying an integer p by one of the numbers 2 to 9. Stan always starts with p = 1,does his multiplication,then Ollie multiplies the number,then Stan and so on. Before a game starts,they draw an integer 1 < n < 4294967295 and the winner is who first reaches p >= n.

 

 

Input

Each line of input contains one integer number n.

 

 

Output

For each line of input output one line either

Stan wins.

or

Ollie wins.
