입력

The only line of input contains a single integer $yy$ ($1995\le y\le 20191995\; \backslash le\; y\; \backslash le\; 2019$), denoting the year. You don't need to process year numbers less than $19951995$ or greater than $20192019$, or incorrect year formats. It is guaranteed that you will be given a number between $19951995$ and $20192019$, inclusive.

Print the winner of the contest in year $yy$ exactly in the same format as in the list above.
