Let's call the following process a transformation of a sequence of length n.

If the sequence is empty, the process ends. Otherwise, append the [greatest common divisor](https://en.wikipedia.org/wiki/Greatest_common_divisor) (GCD) of all the elements of the sequence to the result and remove one arbitrary element from the sequence. Thus, when the process ends, we have a sequence of n integers: the greatest common divisors of all the elements in the sequence before each deletion.

You are given an integer sequence 1, 2, ..., n. Find the lexicographically maximum result of its transformation.

A sequence a_1, a_2, …, a_n is lexicographically larger than a sequence b_1, b_2, …, b_n, if there is an index i such that a_j = b_j for all j < i, and a_i > b_i.

Input

The first and only line of input contains one integer n (1≤ n≤ 10^6).

Output

Output n integers — the lexicographically maximum result of the transformation.

Examples

Input

3


Output

1 1 3 

Input

2


Output

1 2 

Input

1


Output

1 

Note

In the first sample the answer may be achieved this way:

  * Append GCD(1, 2, 3) = 1, remove 2. 
  * Append GCD(1, 3) = 1, remove 1. 
  * Append GCD(3) = 3, remove 3. 



We get the sequence [1, 1, 3] as the result.
