G. The jar of divisors

 

Alice and Bob play the following game. They choose a number N to play with. The rules are as follows:

- They write each number from 1 to N on a paper and put all these papers in a jar.

- Alice plays first, and the two players alternate.

- In his/her turn, a player can select any available number M and remove its divisors including M.

- The person who cannot make a move in his/her turn wins the game.

Assuming both players play optimally, you are asked the following question: who wins the game?

Input

The first line contains the number of test cases T (1 ?≤? T ?≤? 20). Each of the next T lines contains an integer (1 ?≤? N ?≤?1,000,000,000).

Output

Output T lines, one for each test case, containing Alice if Alice wins the game, or Bob otherwise.

Examples
input
2
5
1
output
Alice
Bob

博弈论题目。1就是Bob赢否则就是Alice赢，不知道怎么来的，算了8个发现只有1是Bob赢就这样写了，没想到还真过了。

11         cin>>n;
12         if(n == 1){
13             cout << "Bob\n";
14         }else cout << "Alice\n";
15     }
16     return 0;
