Who has the highest score?

Petryk, Marichka, and Olenka have received their first grades in computer science. They decided that the one with the highest grade will be the winner.

They have asked Serhiy to determine the winner, but since he is busy, they need your help to solve this task.

Input

The first line contains three integers $p$, $m$, $o$ ($1\le p,m,o\le 12$) — representing the grades of Petryk, Marichka, and Olenka, respectively.

It is guaranteed that all grades are distinct.

Output

Print «Petryk» if Petryk has the highest grade, «Marichka» if Marichka has the highest grade, or «Olenka» if Olenka has the highest grade.
