Help the contest archivist to remember the results of each contest and write a program that will read the year and print contest winners of that year in exactly the same format as above.

Input

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

Output

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