Eleven wants to choose a new name for herself. As a bunch of geeks, her friends suggested an algorithm to choose a name for her. Eleven wants her name to have exactly n characters.  [Image] 

Her friend suggested that her name should only consist of uppercase and lowercase letters 'O'. More precisely, they suggested that the i-th letter of her name should be 'O' (uppercase) if i is a member of Fibonacci sequence, and 'o' (lowercase) otherwise. The letters in the name are numbered from 1 to n. Fibonacci sequence is the sequence f where  f_1 = 1,  f_2 = 1,  f_{n} = f_{n} - 2 + f_{n} - 1 (n > 2). 

As her friends are too young to know what Fibonacci sequence is, they asked you to help Eleven determine her new name.


-----Input-----

The first and only line of input contains an integer n (1 ≤ n ≤ 1000).


-----Output-----

Print Eleven's new name on the first and only line of output.


-----Examples-----
