Arnar, Benni and Unnar were at the airport in Barcelona on their way to a competitive programming training camp. When the plane had landed they exited and went to the baggage claim. When they arrived there was no baggage on the conveyor belts. After a few minutes the baggage started trickling in. When Benni noticed this he loudly proclaimed “My bag’s first! No, it’s second first! No... it’s fourth first. No wait...”

Given a list of bags and a number denoting Benni’s bag, can you help Benni find how first his bag is?

Input

First there is a line with two integers $n$ and $k$, the number of bags and Benni’s bag. It will always hold that $1 \leq n \leq 10^5$ and $-10^9 \leq k \leq 10^9$. Next there is a line with $n$ integers separated by spaces, $a_1, a_2, \dotsc , a_ n$. For each $1 \leq i \leq n$ it holds that $-10^9 \leq a_ i \leq 10^9$. No two bags are given by the same number and Benni’s bag always appears in the list.

Output

Print a single line. If Benni’s bag is first print fyrst, if it’s the second print naestfyrst. Otherwise print a single number denoting how first it is followed by the word fyrst after the number.
