题目描述

Alice and Bob are playing a game.

They start with a positive integer nn and take alternating turns doing operations on it. Each turn a player can subtract from nn one of its divisors that isn't 11 or nn . 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 tt ( 1t1041 \leq t \leq 10^4 ) — the number of test cases. Then tt test cases follow.

Each test case contains a single integer nn ( 1n1091 \leq n \leq 10^9 ) — 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.

    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 22 making n=2n = 2 , then Bob cannot make a move so Alice wins.

In the third test case, Alice can subtract 33 so that n=9n = 9 . Bob's only move is to subtract 33 and make n=6n = 6 . Now, Alice can subtract 33 again and n=3n = 3 . Then Bob cannot make a move, so Alice wins.
