Good Game, GG
Description
Alice and Bob are playing a game. Initially there are n positive numbers, the i-th number is ai . In one turn, Alice can choose an odd number and divide it into two positive numbers, or delete a number equals to 1. Bob can choose an even number and divide it into two positive numbers. Two players move in turns, and Alice move first. In one’s turn, if he or she can’t move, he or she lose the game. If two player move optimally, please find out who the winner is.
You need to answer T queries.
Input
First line contains one integer T (1 ≤ T ≤ 10e3 ). In each query: First line contains one integer n (1 ≤ n ≤ 10e5 ). Second line contains n integers, the i-th integer is ai (1 ≤ ai ≤ 10e9 ). The sum of n is less than 2 × 105.
Output
In each query, print Alice if Alice is the winner, print Bob otherwise

Hint
In first query, there are no odd number, Alice can not make a move, so Bob wins.
In second query, Alice can delete 1, the list becomes [2]. Bob can divide 2 into 1, 1, the list becomes [1, 1]. Then, Alice can delete 1, the list becomes [1]. Now Bob can’t make a move, so Alice wins.
