Problem statement
There is a positive integer sequence $a_1, a_2, \ ldots, a_N$ of length $ N $.
Consider the following game, which uses this sequence and is played by $ 2 $ players on the play and the play.
- Alternately select one of the following operations for the first move and the second move.
- Select a positive term in the sequence for $ 1 $ and decrement its value by $ 1 $.
- When all terms in the sequence are positive, decrement the values of all terms by $ 1 $.
The one who cannot operate first is the loser.
When $ 2 $ players act optimally, ask for the first move or the second move.
Constraint
- $1 \ leq N \ leq 2 \ times 10 ^ 5$
- $1 \ leq a_i \ leq 10 ^ 9$
- All inputs are integers
input
Input is given from standard input in the following format.
$ N $
$ a_1 $ $ a_2 $ $ ... $ $ a_N $
output
Output First when the first move wins, and outputSecond when the second move wins.

Output example 1
First
The first move has to reduce the value of the $ 1 $ term by $ 1 $ first, and then the second move has to reduce the value of the $ 2 $ term by $ 1 $.
If the first move then decrements the value of the $ 2 $ term by $ 1 $, the value of all terms in the sequence will be $ 0 $, and the second move will not be able to perform any operations.
