We consider a positive integer perfect, if and only if the sum of its digits is exactly $10$. Given a positive integer $k$, your task is to find the $k$-th smallest perfect positive integer.


-----Input-----

A single line with a positive integer $k$ ($1 \leq k \leq 10\,000$).


-----Output-----

A single number, denoting the $k$-th smallest perfect integer.


-----Examples-----
Input
1

Output
19

Input
2

Output
28



-----Note-----

The first perfect integer is $19$ and the second one is $28$.
