Hackerman wants to know who is the better player between Bob and Alice with the help of a game.

The game proceeds as follows:
First, Alice throws a die and gets the number A
Then, Bob throws a die and gets the number B
Alice wins the game if the sum on the dice is a [prime number]; and Bob wins otherwise.

Given A and B, determine who wins the game.

------ Input Format ------ 

- The first line of input will contain a single integer T, denoting the number of test cases.
- The first and only line of each test case contains two space-separated integers A and B.

------ Output Format ------ 

For each test case, output on a new line the winner of the game: Alice or Bob.

Each letter of the output may be printed in either uppercase or lowercase, i.e, Alice, ALICE, AlIce and aLIcE will all be considered equivalent.

------ Constraints ------ 

$1 ≤ T ≤ 36$
$1 ≤ A ≤ 6$
$1 ≤ B ≤ 6$

----- Sample Input 1 ------ 
3
2 1
1 1
2 2

----- Sample Output 1 ------ 
Alice
Alice
Bob

----- explanation 1 ------ 
Test case $1$: $A = 2$ and $B = 1$. Their sum is $2+1 = 3$ which is a prime number, so Alice wins.

Test case $2$: $A = 1$ and $B = 1$. Their sum is $1+1 = 2$ which is a prime number, so Alice wins.

Test case $3$: $A = 2$ and $B = 2$. Their sum is $2 + 2 = 4$ which is not a prime number, so Bob wins.
