题目描述
Alice and Bob are playing a game.
They start with a positive integer n and take alternating turns doing operations on it. Each turn a player can subtract from n one of its divisors that isn't 1 or n . The player who cannot make a move on his/her turn loses. Alice always moves first.
Note that they subtract a divisor of the current number in each turn.
You are asked to find out who will win the game if both players play optimally.
输入格式
The first line contains a single integer t ( 1≤t≤104 ) — the number of test cases. Then t test cases follow.
Each test case contains a single integer n ( 1≤n≤109 ) — the initial number.
输出格式
For each test case output "Alice" if Alice will win the game or "Bob" if Bob will win, if both players play optimally.
输入输出样例
输入#1
4 1 4 12 69
输出#1
Bob Alice Alice Bob
说明/提示
In the first test case, the game ends immediately because Alice cannot make a move.
In the second test case, Alice can subtract 2 making n=2 , then Bob cannot make a move so Alice wins.
In the third test case, Alice can subtract 3 so that n=9 . Bob's only move is to subtract 3 and make n=6 . Now, Alice can subtract 3 again and n=3 . Then Bob cannot make a move, so Alice wins.
