CF276B.Little Girl and Game

The Little Girl loves problems on games very much. Here's one of them.

Two players have got a string $s$ , consisting of lowercase English letters. They play a game that is described by the following rules:

• The players move in turns; In one move the player can remove an arbitrary letter from string $s$ .
• If the player before his turn can reorder the letters in string $s$ so as to get a palindrome, this player wins. A palindrome is a string that reads the same both ways (from left to right, and vice versa). For example, string "abba" is a palindrome and string "abc" isn't.

Determine which player will win, provided that both sides play optimally well — the one who moves first or the one who moves second.

The input contains a single line, containing string $s$ ( $1<=|s|<=10^{3}$ ). String $s$ consists of lowercase English letters.

In a single line print word "First" if the first player wins (provided that both players play optimally well). Otherwise, print word "Second". Print the words without the quotes.
